Predicate (grammar)

There are two competing notions of the predicate in theories of grammar
Grammar
In linguistics, grammar is the set of structural rules that govern the composition of clauses, phrases, and words in any given natural language. The term refers also to the study of such rules, and this field includes morphology, syntax, and phonology, often complemented by phonetics, semantics,...

). A predicate is seen as a property that is predicated of a subject. A predicate is therefore an expression that can be true of something; Thus, the expression "is moving" is true of those things that are moving. This classical understanding of predicates was adopted more or less directly into Latin and Greek grammars and from there it made its way into English grammars, where it is applied directly to the analysis of sentence structure. It is also the understanding of predicates that we find in dictionaries of the English language. The predicate is one of the two main parts of a sentence

. The predicate serves either to assign a property to a single argument or to relate two or more arguments to each other. Sentences consist of predicates and their arguments (and adjuncts) and are thus predicate-argument structures, whereby a given predicate is seen as linking its arguments into a greater structure. This understanding of predicates sometimes renders a predicate and its arguments in the following manner:

(2) a. Bob laughed. → laughed (Bob)
b. Sam helped us. → helped (Sam, us)
c. Jim gave Jill his dog. → gave (Jim, Jill, his dog)


Predicates are placed on the left outside of brackets, whereas the predicate's arguments are placed inside the brackets. One acknowledges the valency

 of predicates, whereby a given predicate can be monovalent (laughed in 2a), divalent (helped in 2b), trivalent (gave in 2c). These types of representations are analogous to formal semantic analyses, where one is concerned with the proper account of scope facts of quantifiers and logical operators. Concerning basic sentence structure however, these representations suggest above all that verbs are predicates and the noun phrases that they appear with are their arguments. On this understanding of the sentence, the binary division of the clause into subject NP and predicate VP is hardly possible. Instead, the verb is the predicate, and the noun phrases are its arguments.

When auxiliary verbs appear, they are viewed as part of the predicate. The predicates are underlined in the following examples:

(3) a. Bill will have laughed.
b. Will Bill have laughed?
c. We were helped by Sam.
d. Were we helped by Sam?
e. Who did Jim give his dog to?


The understanding of predicates suggested by (3a-e) sees predicates consisting of one main verb and zero, one, two, or more auxiliary verbs. These verbs need not form a string, but they can be interrupted by their arguments. The approach to predicates illustrated with (2-3) is more widespread in Europe, particularly in Germany, where the understanding predicates from traditional grammar

 discussed above seems to hardly exist (for those who know German, see the Wikipedia article in German on the predicate).

There are certainly many questions about this understanding of predicates. For instance, while the predicate nouns and adjectives mentioned above can easily be viewed as forming the predicate, the situation is much less clear for the object NP of a preposition, e.g.

(4) a. The books is on the shelf.
b. The book is on the shelf.


Whether the object NP the shelf should be included in the predicate, as shown in (4a), or excluded from the predicate, as in (4b), is not clear.

This alternative understanding of predicates is more compatible with the dependency grammar

Carlson classes

After the work of Greg N. Carlson, predicates have been divided into the following sub-classes, which roughly pertain to how a predicate relates to its subject:

Stage-level predicates

A stage-level predicate ("s-l predicate" for short) is true of a temporal stage of its subject. For example, if John is "hungry", then he typically will eat some food, which lasts a certain amount of time, and not his entire lifespan.

S-l predicates can occur in a wide range of grammatical constructions and is probably the most versatile kind of predicate.

Individual-level predicates

An individual-level predicate ("i-l predicate") is true throughout the existence of an individual. For example, if John is "smart", this is a property of him, regardless which particular point in time we consider.

I-l predicates are more restricted than s-l ones. I-l predicates can't occur in presentational "there" sentences (a star in front of a sentence indicates that it is odd or ill-formed):
There are police available. ("available" is s-l)
*There are firemen altruistic. ("altruistic" is i-l)


S-l predicates allow modification by manner adverbs and other adverbial modifiers. I-l ones do not.
Tyrone spoke French loudly in the corridor. ("speak French" can be interpreted as s-l)
*Tyrone knew French loudly in the corridor. ("know French" can't be interpreted as s-l)


When an i-l predicate occurs in past tense
Past tense

, it gives rise to what is called a "lifetime effect": The subject must be assumed to be dead or otherwise gone out of existence.
John was available. (s-l no lifetime effect)
John was altruistic. (i-l lifetime effect.)

Kind-level predicates

A kind-level predicate ("k-l predicate") is true of a kind of thing, but cannot be applied to individual members of the kind. An example of this is the predicate "are widespread." One can't meaningfully say of a particular individual John that he is widespread. One may only say this of kinds, as in
Humans are widespread.

 noun phrases are also banned from this environment:
*A cat is widespread. (compare: Nightmares are widespread.)

Collective vs. distributive predicates

Predicates may also be collective or distributive. Collective predicates require their subjects to be somehow plural, while distributive ones don't. An example of a collective predicate is "formed a line". This predicate can only stand in a nexus with a plural subject:
The students formed a line.
*The student formed a line.


Other examples of collective predicates include "meet in the woods", "surround the house", "gather in the hallway" and "carry the piano together". Note that the last one ("carry the piano together") can be made non-collective by removing the word "together". Quantifiers differ with respect to whether or not they can be the subject of a collective predicate. For example, quantifiers formed with "all the" can, while ones formed with "every" or "each" cannot.
All the students formed a line.
All the students gathered in the hallway.
All the students carried a piano together.
*Each student gathered in the hallway.
*Every student formed a line.

 and Japanese verbs behave rather similarly (for example, the negative form of a verb is an adjective), and can be understood as being two forms of predicates; predicate form is referred to as 終止形 (shūshikei, terminal form). Further, unlike in English, Japanese adjectives do not exist independently of predication, and the dictionary form is the predicate form – for example, 小さい (chiisai) is the predicate form of "small", and means "is small", not simply "small". Accordingly, while some textbooks translate Japanese adjectives as English adjectives (translating 小さい as "small"), other textbooks, such as Japanese: The Spoken Language
Japanese: The Spoken Language
Japanese: The Spoken Language is an introductory textbook series for learning Japanese. JSL was written by Eleanor Harz Jorden in collaboration with Mari Noda. Part 1 was published in 1987 by Yale Language Press, Part 2 in 1988, and Part 3 in 1990...
