The elements in European languages indicating the information source are optional and usually do not indicate evidentiality as their primary function — thus they do not form a grammatical category. The obligatory elements of grammatical evidentiality systems may be translated into English, variously, as I hear that, I see that, I think that, as I hear, as I can see, as far as I understand, they say, it is said, it seems, it seems to me that, it looks like, it appears that, it turns out that, alleged, stated, allegedly, reportedly, obviously, etc.

 implications in languages that do not mark evidentiality distinctly from epistemic modality. For example, a person who makes a false statement qualified as a belief may be considered mistaken; a person who makes a false statement qualified as a personally observed fact will probably be considered to have lied.

In some languages, evidential markers also serve other purposes, such as indicating the speakers attitude to, or belief in, the statement. Usually a direct evidential marker may serve to indicate that the speaker is certain about the event stated. Using an indirect evidential marker, such as one for hearsay or reported information, may indicate that the speaker is uncertain about the statement, or doesn't want to take responsibility for its truth. A "hearsay" evidential may then have the undertone of "that's what they say; whether or not it's true is nothing I can take responsibility for". In other languages, this is not the case. Therefore one should distinguish between such evidential markers that only mark source of knowledge, and such evidential markers that serve other functions, such as marking epistemic modality.

Types of grammatical evidentiality

Following the typology
Linguistic typology
Linguistic typology is a subfield of linguistics that studies and classifies languages according to their structural features. Its aim is to describe and explain the common properties and the structural diversity of the world's languages...

 of Aikhenvald (2004, 2006), there are two broad types of evidential marking:
  1. indirectivity marking ("type I")
  2. evidential marking ("type II")


The first type (indirectivity) indicates whether evidence exists for a given statement, but does not specify what kind of evidence. The second type (evidentiality proper) specifies the kind of evidence (such as whether the evidence is visual, reported, or inferred).

Indirectivity (type I)

. These languages indicate whether evidence exists for a given source of information — thus, they contrast direct information (reported directly) and indirect information (reported indirectly, focusing on its reception by the speaker/recipient). Unlike the other evidential "type II" systems, indirectivity marking does not indicate information about the source of knowledge: it is irrelevant whether the information results from hearsay, inference, or perception (however, some Turkic languages distinguish between reported indirect and non-reported indirect, see Johanson 2003, 2000 for further elaboration). This can be seen in the following Turkish

 suffix -di indicates past tense
Past tense
The past tense is a grammatical tense that places an action or situation in the past of the current moment , or prior to some specified time that may be in the speaker's past, present, or future...

. In the second word gelmiş, the suffix -miş also indicates past tense but indirectly. It may be translated into English with the added words obviously or as far as I understand. The direct past tense marker -di is unmarked (or neutral) in the sense that whether or not evidence exists supporting the statement is not specified.

Evidentiality (type II)

The other broad type of evidentiality systems ("type II") specifies the nature of the evidence supporting a statement. These kinds of evidence can be divided into such criteria as:
  • Witness vs. Nonwitness
  • Firsthand vs. Secondhand vs. Thirdhand
  • Sensory
    • Visual vs. Nonvisual (i.e. auditory, olfactory, etc.)
  • Inferential
  • Reportative
    • Hearsay
    • Quotative
  • Assumed


A witness evidential indicates that the information source was obtained through direct observation by the speaker. Usually this is from visual observation (eyewitness), but some languages also mark information directly heard with information directly seen. A witness evidential is usually contrasted with a nonwitness evidential which indicates that the information was not witnessed personally but was obtained through a secondhand source or was inferred by the speaker.

A secondhand evidential is used to mark any information that was not personally observed or experienced by the speaker. This may include inferences or reported information. This type of evidential may be contrasted with an evidential that indicates any other kind of source. A few languages distinguish between secondhand and thirdhand information sources.

Sensory evidentials can often be divided into different types. Some languages mark visual evidence differently from nonvisual evidence that is heard, smelled, or felt. The Kashaya language
Kashaya language

 has a separate auditory evidential.

An inferential evidential indicates information was not personally experienced but was inferred from indirect evidence. Some languages have different types of inferential evidentials. Some of the inferentials found indicate:
  1. information inferred by direct physical evidence,
  2. information inferred by general knowledge,
  3. information inferred/assumed because of speaker's experience with similar situations,
  4. past deferred realization.


In many cases, different inferential evidentials also indicate epistemic modality, such as uncertainty or probability (see evidentiality & epistemic modality below). For example, one evidential may indicate that the information is inferred but of uncertain validity, while another indicates that the information is inferred but unlikely to be true.

Reportative evidentials indicate that the information was reported to the speaker by another person. A few languages distinguish between hearsay evidentials and quotative evidentials. Hearsay indicates reported information that may or may not be accurate. A quotative indicates the information is accurate and not open to interpretation (i.e., is a direct quotation).

Typology of evidentiality systems

The following is a brief survey of evidential systems found in the languages of the world as identified in Aikhenvald (2004). Some languages only have two evidential markers while others may have six or more. The system types are organized by the number of evidentials found in the language. For example, a 2-term system (A) will have two different evidential markers; a 3-term system (B) will have three different evidentials. The systems are further divided by the type of evidentiality that is indicated (e.g., A1, A2, A3, etc.). Languages that exemplify each type are listed in parentheses.

The most common system found is the A3 type.

Evidential-marking & other categories

Evidential systems in many languages are often marked simultaneously with other linguistic categories. For example, a given language may use the same element to mark both evidentiality and mirativity (i.e. unexpected information). This is the case of Western Apache

 systems (through grammatical categories), several languages do mark evidentiality without any grammatical connection to these other semantic/pragmatic systems. More explicitly stated, there are modal systems which do not express evidentiality and evidential systems which do not express modality. Likewise, there are mirative systems which do not express evidentiality and evidential systems which do not express mirativity. Because some languages mark these separately, some linguists (e.g. Aikhenvald, de Haan, DeLancey) argue that evidentiality should be considered a distinct grammatical category, although they also admit the close connection of evidentiality to these other areas of language.

Evidentiality & epistemic modality

Evidentiality is often considered to be a sub-type of epistemic modality (see, for example, Palmer 1986, Kiefer 1994). Other linguists consider evidentiality (marking the source of information in a statement) to be distinct from epistemic modality (marking the degree of confidence in a statement). An English example:
I see that he is coming. (evidential)
I guess that he is coming. (epistemic)


For instance, de Haan (1999, 2001, 2005) states that evidentiality asserts evidence while epistemic modality evaluates evidence and that evidentiality is more akin to a deictic category marking the relationship between speakers and events/actions (like the way demonstrative
Demonstrative

s mark the relationship between speakers and objects, see also Joseph 2003). Aikhenvald (2003) finds that evidentials may indicate a speaker's attitude about the validity of a statement but this is not a required feature of evidentials. Additionally, she finds that evidential-marking may co-occur with epistemic-marking, but it may also co-occur with aspectual/tense or mirative marking.

Considering evidentiality as a type of epistemic modality may only be the result of analyzing non-European languages in terms of the systems of modality found in European languages. For example, the modal verbs in Germanic languages are used to indicate both evidentiality and epistemic modality (and are thus ambiguous when taken out of context). Other (non-European) languages clearly mark these differently. De Haan (2001) finds that the use of modal verbs to indicate evidentiality is comparatively rare (based on a sample of 200 languages).

Terminology

Although some linguists have proposed that evidentiality should be considered separately from epistemic modality, other linguists conflate the two. Because of this conflation, some researchers use the term evidentiality to refer both to the marking of the knowledge source and the commitment to the truth of the knowledge.

Evidentiality in English (non-grammatical)

Evidentiality is not considered a grammatical category in English because it is expressed in diverse ways and is always optional. In contrast, many other languages (including Quechua

) require the speaker to mark the main verb or the sentence as a whole for evidentiality, or offer an optional set of affixes for indirect evidentiality, with direct experience being the default assumed mode of evidentiality.

 sentences:
I am hungry.
Bob is hungry.


We are unlikely to say the second unless someone (perhaps Bob himself) has told us that Bob is hungry. (We might still say it for someone incapable of speaking for himself, such as a baby or a pet.) If we are simply assuming that Bob is hungry based on the way he looks or acts, we are more likely to say something like:
Bob looks hungry.
Bob seems hungry.
Bob would be hungry by now.


Here, the fact that we are relying on sensory evidence, rather than direct experience, is conveyed by our use of the word look or seem.

Another situation in which the evidential modality is expressed in English is in certain kinds of predictions, namely those based on the evidence at hand. Amongst EFL teachers, these are usually referred to as "predictions with evidence". Examples:
Look at those clouds! It's going to rain! (Compare ungrammatical *It will rain!).

Western History of the concept
