. For example, the phrase "the man who wasn't there" contains the noun man, which is modified by the relative clause who wasn't there. A relative clause can also modify a pronoun, as in "he to whom I have written", or a noun phrase which already contains a modifier, as in "the black panther in the tree, which is about to pounce". The complete phrase (modified noun phrase plus modifying relative clause) is also a noun phrase.

Types of relative clause

A relative clause is always used to join together two sentences that share one of their arguments. For example, the sentence "The man that I saw yesterday went home" is equivalent to the following two sentences: "The man went home. I saw the man yesterday." In this case, "the man" occurs as argument to both sentences. Note that there is no requirement that the shared argument fulfills the same role in both of the joined sentences; indeed, in this example, "the man" is subject of the first, but direct object of the second.

The two sentences joined in a relative-clause construction are known as the main clause or matrix clause (the outer clause) and the embedded clause or relative clause (the inner clause). The shared noun as it occurs in the main clause is termed the head noun. Languages differ in many ways in how relative clauses are expressed:
  1. How the role of the shared noun phrase is indicated in the embedded clause.
  2. How the two clauses are joined together.
  3. Where the embedded clause is placed relative to the head noun (in the process indicating which noun phrase in the main clause is modified).


For example, the English sentence "The man that I saw yesterday went home" can be described as follows:
  1. The role of the shared noun in the embedded clause is indicated by gapping (i.e. in the embedded clause "that I saw yesterday", a gap is left after "saw" to indicate where the shared noun would go).
  2. The clauses are joined by the complementizer "that".
  3. The embedded clause is placed after the head noun "the man".


The following sentences indicate various possibilities (only some of which are grammatical in English):
  • "The man [that I saw yesterday] went home". (A complementizer linking the two clauses with a gapping strategy indicating the role of the shared noun in the embedded clause. One possibility in English. Very common cross-linguistically.)
  • "The man [I saw yesterday] went home". (Gapping strategy, with no word joining the clauses—also known as a reduced relative clause

Strategies for indicating the role of the shared noun in the relative clause

There are four main strategies for indicating the role of the shared noun phrase in the embedded clause. These are typically listed in order of the degree to which the noun in the relative clause has been reduced, from most to least:
  1. Gap strategy or gapped relative clause
  2. Relative pronoun
  3. Pronoun retention
  4. Nonreduction

Gapped relative clause

In this strategy, there is simply a gap in the relative clause where the shared noun would go. This is normal in English, for example, and also in Chinese and Japanese. This is the most common type of relative clause, especially in verb-final languages with prenominal relative clauses, but is also widespread among languages with postnominal externally headed relative clauses.

There may or may not be any marker used to join the relative and main clauses. (Note that languages with a case-marked relative pronoun are technically not considered to employ the gapping strategy even though they do in fact have a gap, since the case of the relative pronoun indicates the role of the shared noun.) Often the form of the verb is different from that in main clauses and is to some degree nominalized, as in Turkish and in English reduced relative clause

 with very strong politeness distinctions in their grammars, gapped relative clauses tend however to be restricted to positions high up in the accessibility hierarchy. With obliques and genitives, non-verb-final languages that do not have politeness restrictions on pronoun use tend to use pronoun retention. English is unusual in that all roles in the embedded clause can be indicated by gapping: e.g. "I saw the man who is my friend", but also (in progressively less accessible positions cross-linguistically, according to the accessibility hierarchy described above) "... who I know", "... who I gave a book to", "... who I spoke with", "... who I run slower than".

 the embedded sentence, thereby moving the noun in the embedded sentence into the subject position. This, for example, would transform "The man who I gave a book to" into "The man who was given a book by me". Generally, languages such as this "conspire" to implement general relativization by allowing passivization from all positions – hence a sentence equivalent to "The man who is run slower than by me" is grammatical. Note also that gapping is often used in conjunction with case-marked relative pronouns (since the relative pronoun indicates the case role in the embedded clause), but this is not necessary (e.g. Chinese and Japanese both using gapping in conjunction with an indeclinable complementizer).

Relative pronoun type

This is in fact a type of gapped relative clause, but is distinguished by the fact that the role of the shared noun in the embedded clause is indicated indirectly by the case marking of the marker (the relative pronoun

, have pronoun retention as their sole grammatical type of relative clause.

Nonreduction type

In the nonreduction type, unlike the other three, the shared noun occurs as a full-fledged noun phrase in the embedded clause, which has the form of a full independent clause. Typically, it is the head noun in the main clause that is reduced or missing. Some languages use relative clauses of this type with the normal strategy of embedding the relative clause next to the head noun. These languages are said to have internally headed relative clauses, which would be similar to the (ungrammatical) English structure "[You see the girl over there] is my friend" or "I took [you see the girl over there] out on a date".

. This strategy is equivalent to saying "Which girl you see over there, she is my daughter" or "Which knife I killed my friend with, the police found that knife". It is "correlative" because of the corresponding "which ... that ..." demonstratives or "which ... she/he/it ..." pronouns, which indicate the respective nouns being equated. Note that the shared noun can either be repeated entirely in the main clause or reduced to a pronoun. Note also that there is no need to front the shared noun in such a sentence. For example, in the second example above, Hindi would actually say something equivalent "I killed my friend with which knife, the police found that knife".

Dialects of some European languages, such as Italian, do use the nonreduction type in forms that could be glossed in English as "The man just passed us by, he introduced me to the chancellor here." Similarly, spoken English tends to replace uses of the relative pronoun whose with non-reduced clauses. For example, consider the following sentence:
The man whose daughter I know is arriving tomorrow.

Informal English would tend to say instead
This man, I know his daughter, (and) he's arriving tomorrow.

In general, however, nonreduction is restricted to verb-final languages, though it is more common among those that are head-marking

Strategies for joining the relative clause to the main clause

The following are some of the common strategies for joining the two clauses:
  • Use of an indeclinable particle (specifically, a complementizer

    ) inserted into the sentence, placed next to the modified noun; the embedded clause is likewise inserted into the appropriate position, typically placed on the other side of the complementizer. This strategy is very common and arguably occurs in English with the word that ("the main that I saw"), though this interpretation of "that" as something other than a relative pronoun is controversial (see below).

Languages which cannot relativize directly on noun phrases low in the accessibility hierarchy can sometimes use alternative voices to "raise" the relevant noun phrase so that it can be relativized. The most common example is the use of applicative voice

 are used to raise ergative arguments to absolutive.

For example, a language that can relativize only subjects could say this:
  • The girl [who likes me] came to visit.

But not:
  • *The girl [who I like] came to visit.
  • *The girl [who I gave a rose to] came to visit.
  • *The girl [who I watched a movie with] came to visit.
  • *The girl [whose father I know] came to visit.
  • *The girl [who I know the father of] came to visit. (equivalent to previous)
  • *The girl [who I am taller than] came to visit.

These languages might form an equivalent sentence by passivization

Passive voice is a grammatical voice common in many of the world's languages. Passive is used in a clause whose subject expresses the theme or patient of the main verb. That is, the subject undergoes an action or has its state changed. A sentence whose theme is marked as grammatical subject is...

:
  • The girl [who was liked by me] came to visit.
  • The girl [who was given a rose by me] came to visit.
  • The girl [who was watched a movie with by me] came to visit.
  • The girl [who was known the father of by me] came to visit.
  • The girl [who was been taller than by me] came to visit.

Note that these passivized sentences get progressively more ungrammatical in English as they move down the accessibility hierarchy; the last two, in particular, are so ungrammatical as to be almost unparsable by English speakers. However, those languages with severe restrictions on which roles can be relativized are precisely those that can passivize almost any position, and hence the last two sentences would be normal in these languages.

A further example is languages that can relativize only subjects and direct objects. Hence the following would be possible:
  • The girl [who I like] came to visit.

However, the other ungrammatical examples above would still be ungrammatical. These languages often allow an oblique object to be moved to the direct object slot by the use of the so-called applicative voice

Rank or the Relational Hierarchy.

English

In English, a relative clause follows the noun it modifies. It is generally indicated by a relative pronoun at the start of the clause, although sometimes simply by word order. If the relative pronoun is the object of the verb in the relative clause, it comes at the beginning of the clause even though it would come at the end of an independent clause ("He is the man whom I saw", not "He is the man I saw whom").

The choice of relative pronoun can be affected by whether the clause modifies a human or non-human noun, by whether the clause is restrictive or not, and by the role (subject, direct object, or the like) of the relative pronoun in the relative clause.
  • For a human antecedent, "who" or "whom" is usually used ("He is the person who saw me", "He is the person who(m) I saw"), although occasionally "that" is used instead. For a non-human antecedent, "that" or "which" is used.

  • In a non-restrictive clause with a non-human antecedent, "which" is used ("The tree, which has fallen, is over there"), while in a restrictive clause with a non-human antecedent "that" or "which" is used ("The tree that fell is over there", "The tree which fell is over there") (although some prescriptive grammars require the use of "that" in this context).

  • The relative pronoun "who(m)" has a subjective case form "who" that must be used if it is the subject of the relative clause ("He is the person who saw me"), and an objective case form which in formal usage is used as the object of a verb or preposition in the relative clause ("He is the person whom I saw", "He is the person whom I talked to", "He is the person to whom I talked"); but in informal usage "whom" is often replaced by "who".


In English, as in some other languages (such as French; see below), non-restrictive
Restrictiveness
In semantics, a modifier is said to be restrictive if it restricts the reference of its head. For example, in "the red car is fancier than the blue one", red and blue are restrictive, because they restrict which cars car and one are referring to...

 relative clauses are set off with commas, but restrictive ones are not:
  • "I met a man and a woman yesterday. The woman, who had a thick French accent, was very pretty." (non-restrictive — does not narrow down who is being talked about)
  • "I met two women yesterday, one with a thick French accent and one with a mild Italian one. The woman who had the thick French accent was very pretty." (restrictive — adds information about who is being referred to)


As regards relative clauses, English has two particularities that are unique among the Germanic languages:
  1. In other Germanic languages, if a relative pronoun is the object of a preposition in the relative clause, then the preposition always appears at the start of the clause, before the relative pronoun. In English, the preposition will often appear where it would appear if the clause were an independent clause — in other words, the relative pronoun "strands" it when it moves to the start of the clause. For example, in "That is the doctrine I believe in", "in" appears in the same place (clause-final) as it does is the independent clause "I believe in it." This construction is equivalent in meaning to "That is the doctrine in which I believe", and both are correct in English. It used to be common to regard the position-final preposition usage as a grammatical error (see: linguistic prescription
    Linguistic prescription
    In linguistics, prescription denotes normative practices on such aspects of language use as spelling, grammar, pronunciation, and syntax. It includes judgments on what usages are socially proper and politically correct...

    ) but in fact it has been a standard feature of the language since the times of Middle English
    Middle English
    Middle English is the stage in the history of the English language during the High and Late Middle Ages, or roughly during the four centuries between the late 11th and the late 15th century....

    .
  2. In other Germanic languages, a relative pronoun is always necessary. In English, however, it may be suppressed in a restrictive clause (as in "The man [whom] we met was very friendly"), provided it would not serve as the subject of the main verb (the relative pronoun is mandatory in "He is the person who saw me"). When the relative pronoun is omitted, if in the unsuppressed counterpart the relative pronoun is the object of a preposition in the relative clause, then said preposition is always "stranded" in the manner described above ("That is the doctrine I believe in"); it is never moved to the start of the clause (so "That is the doctrine in I believe" never occurs).


The status of "that" as a relative pronoun is not universally agreed. Traditional grammars treat "that" as a relative pronoun, but not all contemporary grammars do: e.g. the Cambridge Grammar of the English Language (pp. 1056–7) makes a case for treating "that" as a subordinator instead of a relative pronoun; and the British National Corpus

The British National Corpus is a 100-million-word text corpus of samples of written and spoken English from a wide range of sources. It was compiled as a general corpus in the field of corpus linguistics...

 treats "that" as a subordinating conjunction even when it introduces relative clauses. One motivation for the different treatment of "that" is that there are differences between "that" and "which" (e.g., one can say "in which" but not "in that", etc.).

 is as complicated as, but similar in many ways to, the system in English.

When the pronoun is to act as the direct object of the relative clause, is generally used, although , which is inflected for grammatical gender and number, is sometimes used in order to give more precision. For example, any of the following is correct and would translate to "I talked to his/her father and mother, whom I already knew":


However, in the first sentence, "whom I already knew" refers only to the mother; in the second, it refers to both parents; and in the third, as in the English sentence, it could refer either only to the mother, or to both parents.

When the pronoun is to act as the subject of the relative clause, is generally used, though as before, may be used instead for greater precision. (This is less common than the use of with direct objects, however, since verbs in French often reflect the grammatical number of their subjects.)

When the pronoun is to act in a possessive sense, where the preposition de (of/from) would normally be used, the pronoun ("whose") is used, but does not act as a determiner for the noun "possessed":
("I spoke with a woman whose son I work with." - lit., "I spoke with a woman of whom I work with the son.")


This construction is also used in non-possessive cases where the pronoun replaces an object marked by :
("That's the man of whom I spoke.")


More generally, in modern French, can signal the topic of the following clause, without replacing anything in this clause:
("That's a man about whom I believe that he must make a lot of money.")


When the pronoun is to act as the object of a preposition (other than when is used), is generally used, though can be used if the antecedent is human. The preposition always appears before the pronoun, and the prepositions and (at/to) contract with to form and , or with to form and .

German

Aside from their highly inflected forms, German
German language
German is a West Germanic language, related to and classified alongside English and Dutch. With an estimated 90 – 98 million native speakers, German is one of the world's major languages and is the most widely-spoken first language in the European Union....

 relative pronouns are less complicated than English.  There are two varieties.  The more common one is based on the definite article der, die, das, but with distinctive forms in the genitive (dessen, deren) and in the dative plural (denen).  Historically this is related to English that.  The second, which is more literary and used for emphasis, is the relative use of welcher, welche, welches, comparable with English which. As in most Germanic languages, including Old English, both of these inflect according to gender, case and number. They take their gender and number from the noun they modify, but the case from their function in their own clause.
Das Haus, in dem ich wohne, ist sehr alt.
The house in which I live is very old.


The relative pronoun dem is neuter singular to agree with Haus, but dative because it follows a preposition in its own clause.  On the same basis, it would be possible to substitute the pronoun welchem.

However, German uses the uninflecting was ('what') as a relative pronoun when the antecedent is alles, etwas or nichts ('everything', 'something', 'nothing'.).
Alles, was Jack macht, gelingt ihm.
Everything that Jack does is a success.


In German, all relative clauses are marked with commas.

Indirect relative clauses are formed with a relativizer

 at the beginning; the relativized element remains in situ in the relative clause.

Irish
an fear a bhfuil a iníon san ospidéal
the man IND-REL is his daughter in the hospital
"the man whose daughter is in the hospital"

Welsh
y dyn y rhois y llyfr iddo
the man IND-REL I gave the book to him
"the man to whom I gave the book"


Note that although both the Irish relative pronoun and the relativizer are 'a', the relative pronoun triggers lenition of a following consonant, while the relativizer triggers eclipsis (see Irish initial mutations
Irish initial mutations
Irish, like all modern Celtic languages, is characterized by its initial consonant mutations. These mutations affect the initial consonant of a word under specific morphological and syntactic conditions...

).

Both direct and indirect relative particles can be used simply for emphasis, often in answer to a question or as a way of disagreeing with a statement. For instance, the Welsh example above, "y dyn a welais" means not only "the man whom I saw", but also "it was the man (and not anyone else) I saw"; and "y dyn y rhois y llyfr iddo" can likewise mean "it was the man (and not anyone else) to whom I gave the book".

. In later times, asher became interchangeable with the prefix she- (which is also used as a conjunction, with the sense of English that), and in Modern Hebrew, this use of she- is much more common than asher, except in some formal, archaic, or poetic writing. In meaning, the two are interchangeable; they are used regardless of whether the clause is modifying a human, regardless of their grammatical case in the relative clause, and regardless of whether the clause is restrictive.

Further, because Hebrew does not generally use its word for is, she- is used to distinguish adjective phrases used in epithet from adjective phrases used in attribution:
Ha-kise l'-yad-kha. ("The chair is next to you." - lit., "The-chair [is] to-hand-your.")
Ha-kise she-l'-yad-kha shavur. ("The chair next to you is broken." - lit., "The-chair that-[is]-to-hand-your [is] broken.")


(This use of she- does not occur with simple adjectives, as Hebrew has a different way of making that distinction. For example, Ha-kise adom means "The chair [is] red," while Ha-kise ha-adom shavur means "The red chair is broken" - literally, "The chair the red [is] broken.")

Since 1994, the official rules of Modern Hebrew (as determined by the Academy of the Hebrew Language
Academy of the Hebrew Language
The Academy of the Hebrew Language was established by the Israeli government in 1953 as the "supreme institution for scholarship on the Hebrew language."-History:...

) have stated that relative clauses are to be punctuated in Hebrew the same way as in English (described above). That is, non-restrictive clauses are to be set off with commas, while restrictive clauses are not:
Ha-kise, she-ata yoshev alav, shavur. ("The chair, which you are sitting on, is broken.")
Ha-kise she-ata yoshev alav shavur. ("The chair that you are sitting on is broken.")


Nonetheless, many, perhaps most, speakers of Modern Hebrew still use the pre-1994 rules, which were based on the German rules (described above). Except for the simple adjective-phrase clauses described above, these speakers set off all relative clauses, restrictive or not, with commas:
Ha-kise, she-ata yoshev alav, shavur. ("The chair that you are sitting on is broken," or "The chair, which you are sitting on, is broken.")


One major difference between relative clauses in Hebrew and those in (for example) English is that in Hebrew, what might be called the "regular" pronoun is not always suppressed in the relative clause. To reuse the prior example:
Ha-kise, she-ata yoshev alav, shavur. (lit., "The chair, which you are sitting on it, [is] broken.")


More specifically, if this pronoun is the subject of the relative clause, it is always suppressed. If it is the direct object, then it is usually suppressed, though it is also correct to leave it in. (If it is suppressed, then the special preposition et, used to mark the direct object, is suppressed as well.) If it is the object of a preposition, it must be left in, because in Hebrew - unlike in English - a preposition cannot appear without its object. When the pronoun is left in, she- might more properly be called a relativizer

Arabic

In Literary Arabic there is a relative pronoun (in Arabic: ) allaḏī (masculine singular), feminine singular allatī, masculine plural allaḏīna, feminine plural allawātī, masculine dual allaḏānī (nominative) / allaḏayni (accusative and genitive), feminine dual allatānī (nom.) / allataynī (acc. and gen.).

Its usage has two specific rules: it agrees with the antecedent in gender, number and case, and it is used only if the antecedent is definite. If the antecedent is indefinite, no relative pronoun is used. The former is called jumlat sila (conjunctive sentence) while the latter is called jumlat sifa (descriptive sentence).
al-waladu (a)lladhi ra’aytuhu fī (a)ṣ-ṣaffi ’amsi ğā’ibun al-yawma
"The boy I saw in class yesterday is missing today". (relative pronoun present)
hāḏā waladun ra’aytu-hu fī (a)ṣ-ṣaffi ’amsi
"This is a boy I saw in class yesterday". (relative pronoun absent)


In Demotic Arabic the multiple forms of the relative pronoun have been levelled in favour of a single form, a simple conjunction, which in most dialects is illi, and is never omitted. So in Palestinian Arabic the above sentences would be:
  • alwalad illi shuftō fi (a)ssaff embārih ghāyeb alyōm
  • hāda walad illi shuftō fi (a)ssaff embārih


As in Hebrew, the regular pronoun referring to the antecedent is repeated in the relative clause - literally, "the boy whom I saw him in class..." (the -hu in ra'aituhu and the in shuftō). The rules of suppression in Arabic are identical to those of Hebrew: obligatory suppression in the case that the pronoun is the subject of the relative clause, obligatory retention in the case that the pronoun is the object of a preposition, and at the discretion of the speaker if the pronoun is the direct object. The only difference from Hebrew is that, in the case of the direct object, it is preferable to retain the pronoun rather than suppress it.

Japanese

Japanese does not employ relative pronouns to relate relative clauses to their antecedents. Instead, the relative clause directly modifies the noun phrase as an attributive verb
Attributive verb
In grammar, an attributive verb is a verb which modifies a noun as an attributive, rather than expressing an independent idea as a predicate....

, occupying the same syntactic space as an attributive adjective (before the noun phrase).
この おいしい 天ぷら
kono oishii tempura
"this delicious tempura
Tempura
], is a Japanese dish of seafood or vegetables that have been battered and deep fried.-Batter:A light batter is made of cold water and soft wheat flour . Eggs, baking soda or baking powder, starch, oil, and/or spices may also be added...

"

姉が 作った 天ぷら
ane-ga tsukutta tempura
sister-SUBJ make-PAST tempura
"the tempura [that] my sister made"

天ぷらを 食べた 人
tempura-o tabeta hito
tempura-OBJ eat-PAST person
"the person who ate the tempura"


In fact, since so-called i-adjectives in Japanese are technically intransitive stative verbs, it can be argued that the structure of the first example (with an adjective) is the same as the others. A number of "adjectival" meanings, in Japanese, are customarily shown with relative clauses consisting solely of a verb or a verb complex:
光っている ビル
hikatte-iru biru
lit-be building
"an illuminated building"

濡れている 犬
nurete-iru inu
be_wet-be dog
"a wet dog"


Often confusing to speakers of languages which use relative pronouns are relative clauses which would in their own languages require a preposition with the pronoun to indicate the semantic relationship among the constituent parts of the phrase.
紅茶を 淹れる ために お湯を 沸かした やかん
kōcha-o ireru tame ni oyu-o wakashita yakan
tea-OBJ make purpose for hot-water-OBJ boiled kettle
"the kettle I boiled water in for tea"


Here, the preposition "in" is missing from the Japanese ("missing" in the sense that the corresponding postposition would be used with the main clause verb in Japanese) Common sense indicates what the meaning is in this case, but the "missing preposition" can sometimes create ambiguity.
天ぷらを 作った 人
tempura-o tsukutta hito
tempura-OBJ made person "the person who made the tempura" "the person [someone] made the tempura for"


In this case, (1) is the context-free interpretation of choice, but (2) is possible with the proper context.
僕が 記事を 書いた レストラン
boku-ga kiji-o kaita resutoran
I-SUBJ article-OBJ wrote restaurant "a restaurant about which I wrote an article" "a restaurant in which I wrote an article"


Without more context, both (1) and (2) are equally viable interpretations of the Japanese.

Note: Spaces are not ordinarily used in Japanese, but they are supplemented here to facilitate parsing by non-speakers of the language.

Georgian is the native language of the Georgians and the official language of Georgia, a country in the Caucasus.Georgian is the primary language of about 4 million people in Georgia itself, and of another 500,000 abroad...

, there are two strategies for forming relative clauses. The first is similar to that of English or Latin: the modified noun is followed by a relativizer that inflects for its embedded case and may take a postposition. The relativized noun may be preceded by a determiner.
(ის) კაცი, რომელიც პარკში წავიდა, გაზეთს კითხულობს
(is) ḳac-i, romel-i-c ṗarḳ=ši c̣avida, gazet-s ḳitxulobs

(that.NOM) woman-NOM which-DAT-REL letter-DAT I.will.write.it.to.her Tbilisi-in she.lives
"the woman who I will write a letter to lives in Tbilisi
Tbilisi
Tbilisi is the capital and the largest city of Georgia, lying on the banks of the Mt'k'vari River. The name is derived from an early Georgian form T'pilisi and it was officially known as Tiflis until 1936...

"

ნინომ (ის) სკამი, რომელზეც ვზივარ, იყიდა
Nino-m (is) sḳam-i, romel=ze-c vzivar, iqida
Nino-ERG (that.NOM) chair-NOM which=on-REL I.sit she.bought.it
"Nino bought the chair I am sitting in"


A second, more colloquial, strategy is marked by the invariant particle რომ rom. This particle is generally the second word of the clause, and since it does not decline, is often followed by the appropriately cased third-person pronoun to show the relativized noun's role in the embedded clause. A determiner precedes the relativized noun, which is also usually preceded by the clause as a whole.
წერილს რომ მას დავუწერ, ის ქალი თბილისში ცხოვრობს
c̣̣eril-s rom mas davuc̣̣er, is kal-i tbilis=ši cxovrobs
letter-DAT REL 3S.DAT I.will.write.it.to.her that.NOM woman-NOM Tbilisi-in she.lives
"the woman who I will write a letter to lives in Tbilisi

1S REL 3S.DAT=on I.sit that.NOM chair-NOM Nino-ERG she.bought.it
"Nino bought the chair I am sitting in"


Such relative clauses may be interally-headed. In such cases, the modified noun moves into the clause, taking the appropriate declension for the its role therein (thus eliminating the need for the third person pronouns in the above examples), and leaves behind the determiner (which now functions as a pronoun) in the matrix clause.
ქალს რომ წერილს დავუწერ, ის თბილისში ცხოვრობს

 uses the gapping strategy to form relative clauses, with the complementiser
Complementizer
In linguistics , a complementizer is a syntactic category roughly equivalent to the term subordinating conjunction in traditional grammar. For example, the word that is generally called a complementizer in English sentences like Mary believes that it is raining...

, na / =ng 'that', separating the head, which is the noun being modified, from the actual relative clause. In (1a) below, lalaki 'man' serves as the head, while nagbigay ng bigas sa bata 'gave rice to the child' is the relative clause.
(1) a. lalaki =ng nagbigay ____ ng bigas sa bata
man .gave rice child
"man that gave rice to the child"
b. Nagbigay ang lalaki ng bigas sa bata.
.gave man rice child
"The man gave rice to the child."


The gap inside the relative clause corresponds to the position that the noun acting as the head would have normally taken, had it been in a declarative sentence. In (1a), the gap is in subject position within the relative clause. This corresponds to the subject position occupied by ang lalaki 'the man' in the declarative sentence in (1b).

There is a constraint in Tagalog on the position from which a noun can be relativised and in which a gap can appear: A noun has to be the subject within the relative clause in order for it to be relativised. The phrases in (2) are ungrammatical because the nouns that have been relativised are not the subjects of their respective relative clauses. In (2a), the gap is in direct object position, while in (2b), the gap is in indirect object position.
(2) a. * bigas na nagbigay ang lalaki ____ sa bata
rice .gave man child
for: "rice that the man gave to the child"
b. * bata =ng nagbigay ang lalaki ng bigas ____
rice .gave man rice
for: "child that the man gave rice to"


The correct Tagalog translations for the intended meanings in (2) are found in (3), where the verbs have been passivised in order to raise the logical direct object in (3a) and the logical indirect object in (3b) to subject position. (Tagalog can have more than one passive voice form for any given verb.)
(3) a. bigas na ibinigay ng lalaki sa bata
rice .gave man child
"rice that the man gave to the child"
(or: "rice that was given to the child by the man")
b. bata =ng binigyan ng lalaki ng bigas
child gave. man rice
"child that the man gave rice to"
(or: "child that was given rice to by the man")


Tagalog relative clauses can be left-headed, as in (1a) and (3), right-headed, as in (4), or internally headed, as in (5).
(4) nagbigay ng bigas sa bata na lalaki
.gave rice child man
"man that gave rice to the child"

(5) a. nagbigay na lalaki ng bigas sa bata
.gave man rice child
"man that gave rice to the child"
b. nagbigay ng bigas na lalaki sa bata
.gave rice man child
"man that gave rice to the child"


In (4), the head, lalaki 'man', is found after or to the right of the relative clause, nagbigay ng bigas sa bata 'gave rice to the child'. In (5), the head is found in some position inside the relative clause. Note that when the head appears to the right of or internally to the relative clause, the complementiser appears to the left of the head. When the head surfaces to the left of the relative clause, the complementiser surfaces to the right of the head.

There are exceptions to the subjects-only constraint to relativisation mentioned above. The first involves relativising the possessor

 of a noun phrase within the relative clause.
(6) bata =ng nasugatan ang daliri ____
child injured. finger
"child whose finger was injured"


In (6), the head, bata 'child', is the owner of the injured finger. Note that ang daliri 'the finger' is the subject of the verb, nasugatan 'was injured'.

Another exception involves relativising the oblique

 noun phrase.
(7) a. ospital (na) kung saan ipinanganak si Juan

b. Nagtanong siya kung saan ipinanganak si Juan.

"She asked where Juan was born."
c. Ipinanganak si Juan sa ospital.
.bore Juan hospital
"Juan was born at the hospital."
d. Saan ipinanganak si Juan?
where .bore Juan
"Where was Juan born?"


When an oblique noun phrase is relativised, as in (7a), na 'that', the complementiser that separates the head from the relative clause, is optional. The relative clause itself is also composed differently. In the examples in (1a), and in (3) to (6), the relative clauses are simple declaratives that contain a gap. However, the relative clause in (7a) looks more like an indirect

  are avoided unless they are short.

If in English a relative clause would have a copula and an adjective, in Hawaiian the antecedent is simply modified by the adjective: "The honest man" instead of "the man who is honest". If the English relative clause would have a copula and a noun, in Hawaiian an appositive is used instead: "Paul, an apostle" instead of "Paul, who was an apostle".

If the English relative pronoun would be the subject of an intransitive or passive verb, in Hawaiian a participle is used instead of a full relative clause: "the people fallen" instead of "the people who fell"; "the thing given" instead of "the thing that was given". But when the relative clause's antecedent is a person, the English relative pronoun would be the subject of the relative clause, and the relative clause's verb is active and transitive, a relative clause is used and it begins with the relative pronoun nana: The one who me (past) sent = "the one who sent me".

If in English a relative pronoun would be the object of a relative clause, in Hawaiian the possessive form is used so as to treat the antecedent as something possessed: the things of me to have seen = "the things that I saw"; Here is theirs to have seen = This is what they saw".

Mandarin

In Mandarin Chinese, the relative clause precedes the noun that it modifies, and ends with the relative particle de. If the relative clause is missing a subject but contains an object (if transitive), the main-clause noun is the implied subject of the relative clause:
zhòng shuǐguǒ de nóngrén
grow fruit (particle) farmer
the farmer who grows fruit


If the object but not the subject is missing from the relative clause, the main-clause noun is the implied object of the relative clause:
tāmen zhòng de shuǐguǒ
they grow (particle) fruit
the fruit that they grow


If both the subject and the object are missing from the relative clause, then the main-clause noun could either be the implied subject or the implied object of the relative clause; sometimes which is intended is clear from the context, especially when the subject or object of the verb must be human and the other must be non-human:
jīntiān yíng de qián fù fáng zū
today win (particle) money pay house rent
the money that [we] won today pays the rent


But sometimes ambiguity arises when it is not clear from the context whether the main-clause noun is intended as the subject or the object of the relative clause:
zuótiān pīping de rén dōu bu zài zhèlǐ
yesterday criticize (particle) person all not at here
the people who criticized [others] yesterday are not all here OR the people whom [others] criticized yesterday are not all here


Sometimes a relative clause has both a subject and an object specified, in which case the main-clause noun is the implied object of an implied preposition in the relative clause:
wŏ xiě xìn de máobǐ
I write letter (particle) brushpen
the brushpen I write letters with

Creole language
A creole language, or simply a creole, is a stable natural language developed from the mixing of parent languages; creoles differ from pidgins in that they have been nativized by children as their primary language, making them have features of natural languages that are normally missing from...

 also called Hawaiian Pidgin or simply Pidgin, relative clauses work in a way that is similar to, but not identical to, the way they work in English. As in English, a relative pronoun that serves as the object of the verb in the relative clause can optionally be omitted: For example,
Ai neva si da buk daet Lisa wen bai
I never see the book that Lisa (past) buy
I didn't see the book that Lisa bought


can also be expressed with the relative pronoun omitted, as
Ai neva si da buk Lisa wen bai
I never see the book Lisa (past) buy
I didn't see the book Lisa bought


However, relative pronouns serving as the subject of a relative clause show more flexibility than in English; they can be included, as is mandatory in English, they can be omitted, or they can be replaced by another pronoun. For example, all of the following can occur and all mean the same thing:
Get wan nada grl hu no kaen ste stil
There's one other girl who no can stay still
There's another girl who cannot stay still

Get wan nada grl no kaen ste stil
There's one other girl no can stay still

Get wan nada grl shi no kaen ste stil
There's one other girl she no can stay still
