of evidentiality that is required to be expressed at all times. In contrast, 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.

that are added to verbs: (nonvisual sensory), (inferential), (hearsay), and (direct knowledge).
Many languages with grammatical evidentiality mark evidentiality independently from
tense-
aspect or
epistemic modality
Epistemic modality is a sub-type of linguistic modality that encompasses knowledge, belief, or credence in a proposition. Epistemic modality is exemplified by the English modal verb, modals ''may'', ''might'', ''must''. However, it occurs cross-li ...
, which is the speaker's evaluation of the information, i.e. whether it is reliable, uncertain, probable.
The use of evidentiality has
pragmatic 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, while a person who makes a false statement qualified as a personally observed fact will probably be considered to have lied. More generally, a speaker of a language that does have obligatory grammatical evidentiality is required to cognitively engage with the source of their belief of any statement in a manner that the speaker of languages without obligatory evidentiality may gloss over.
In some languages, evidential markers also serve other purposes, such as indicating the speaker's attitude towards, 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.
Evidentials can also be used to "deflect culpability" in a statement. In his dissertation on
Nanti, a Peruvian Amazonian language, Lev Michael refers to an example in which a young girl is accidentally burned, and a community member questions her mother about how it happened. Her mother uses the evidential marker which translates to "presumably," to deflect responsibility for the girl's mistake.
Some languages are borderline cases. For example, the
Romance languages
The Romance languages, also known as the Latin or Neo-Latin languages, are the languages that are Language family, directly descended from Vulgar Latin. They are the only extant subgroup of the Italic languages, Italic branch of the Indo-E ...
are mostly like English in not having grammatical evidentiality, but do have a
conditional mood
The conditional mood (abbreviated ) is a grammatical mood used in conditional sentences to express a proposition whose validity is dependent on some condition, possibly counterfactual.
It may refer to a distinct verb form that expresses the condit ...
which has three uses: conditions, future-in-the-past, and hearsay. Thus in journalistic
French, there is frequently a distinction between and : both translate to "He has admitted his guilt," but with an implication of certainty with the first, and the idea of "reportedly" with the second. The same happens in
Spanish ( vs. ) and in
Portuguese ( vs. ).
Aikhenvald identified five semantic categories that recurrently occur across languages of the world:
*Visual Sensory
*Non-Visual Sensory
*Inferentials
*Hearsay Reportatives
*Quotative Reportatives
No language has been reported to have special forms for smell, taste or feeling although these may be covered by non-visual evidentials.

, there are two broad types of evidential marking:
# indirectivity marking ("type I")
# 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)
''Indirectivity'' (also known as ''inferentiality'') systems are common in
Uralic and
Turkic languages

. 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, an 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 verbs:

The past tense is a grammatical tense whose function is to place an action or situation in the past. Examples of verbs in the past tense include the English verbs ''sang'', ''went'' and ''washed''. Most languages have a past tense, with some hav ...
. In the second word , the suffix also indicates past tense but ''indirectly''. It may be translated into English with the added phrases 'obviously', 'apparently' or 'as far as I understand'. The direct past tense marker 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 categories as:
:* Sensory
:** Visual
:** Non-visual
:* Inferential
:* Assumed
:* Reportative
:** Hearsay
:** Quotative
''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 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:
:# Information inferred by direct physical evidence
:# Information inferred by general knowledge
:# Information inferred/assumed because of speaker's experience with similar situations
:# Past deferred realization
In many cases, different inferential evidentials also indicate epistemic modality, such as uncertainty or probability (see

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 two-term system (''A'') will have two different evidential markers; a three-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.
Two-term systems:

Evidentiality marking and other categories
Evidential systems in many languages are often marked simultaneously with other linguistic categories. For example, according to Aikhenvald, a given language may use the same element to mark both evidentiality and
mirativity

or
pragmatic systems (through grammatical categories), Aikhenvald believes that several languages do mark evidentiality without any grammatical connection to these other semantic/pragmatic systems. More explicitly stated, she believes that 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.
Aside from those,
egophoricity may interact with evidentiality as well.

Epistemic modality
Evidentiality is often considered to be a sub-type of

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 know that he is coming. (epistemic)
For instance, de Haan states that evidentiality ''asserts'' evidence while epistemic modality ''evaluates'' evidence and that evidentiality is more akin to a
deictic
In linguistics, deixis () is the use of words or phrases to refer to a particular time (e.g. ''then''), place (e.g. ''here''), or person (e.g. ''you'') relative to the context of the utterance. Deixis exists in all known natural languagesLyons, J ...

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).
Clause type
Evidential categories are more likely to be marked in a main declarative
clause
In language, a clause is a Constituent (linguistics), constituent or Phrase (grammar), phrase that comprises a semantic predicand (expressed or not) and a semantic Predicate (grammar), predicate. A typical clause consists of a subject (grammar), ...
than in the other types of clauses. In some languages, however, evidential forms may appear in questions or commands as well.
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.
In English (not grammaticalized)
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,
Aymara, and
Yukaghir) 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.
Consider these
English 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 themself, 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.
: Bob
must 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. These can be referred to as "predictions with evidence". Examples:
: Look at those clouds! It's going to rain! (Compare "It will rain!").
Possible exceptions
The suffix "-ish" can be considered to be a
grammaticalized marker of uncertainty.
Western history of the concept
The notion of evidentiality as obligatory grammatical information was first made apparent in 1911 by
Franz Boas

Jakobson also was the first to clearly separate evidentiality from

Systems of evidentiality have received focused linguistic attention only relatively recently. The first major work to examine evidentiality cross-linguistically is Chafe & Nichols (1986). A more recent
typological comparison is Aikhenvald (2004).
