In
linguistics, 'evidentiality' is, broadly, the indication of the nature of evidence for a given statement, that is, whether
evidence exists for the statement and/or what kind of evidence exists. An 'evidential' is the particular
grammatical element (
affix,
clitic, or
particle) that indicates evidentiality.
Introduction
All languages have some means of specifying the source of information. European languages (such as
Germanic and
Romance languages) often indicate evidential-type information through
modal verbs (
French: ''devoir'',
Dutch: ''zouden'',
Danish: ''skulle'',
German: ''sollen'') or other
lexical words (
adverbials) (
English: ''reportedly'') or phrases (English: ''it seems to me'').
The use of evidentiality has
pragmatic implications. 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.
Some languages have a distinct
grammatical category of evidentiality that is required to be expressed at all times. 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.
Aikhenvald (2004) reports that about a quarter of the world's languages have some type of grammatical evidentiality. She also reports that, to her knowledge, no research has been conducted on grammatical evidentiality in
sign languages.
Many languages with grammatical evidentiality mark evidentiality independently from
tense-
aspect or
epistemic modality (which is the speaker's evaluation of the information, i.e. whether it is reliable, uncertain, probable).
Grammatical evidentiality may be expressed in different forms (depending on the language), such as through
affixes,
clitics, or
particles. For example,
Eastern Pomo has 4 evidential
suffixes that are added to verbs, ''-ink’e'' (nonvisual sensory), ''-ine'' (inferential), ''-·le'' (hearsay), ''-ya'' (direct knowledge).
Evidentials in Eastern Pomo| Evidential type | Example Verb | Gloss |
|---|
| nonvisual sensory | | "burned"
[speaker felt the sensation] |
| inferential | | "must have burned"
[speaker saw circumstantial evidence] |
| hearsay (reportative) | | "burned, they say"
[speaker is reporting what was told] |
| direct knowledge | | "burned"
[speaker has direct evidence, probably visual] |

Types of grammatical evidentiality
Following the
typology of Aikhenvald (2003, 2004), 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'' systems are common in
Iranian,
Finno-Ugric, 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, 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:
:
| gel'-di' | "came" | | | gel'-miş' | "obviously came, came (as far as understood)" |
| come-PAST | | | | come-INDIRPAST | |
:
(Johanson 2003: 275)
In the first word ''geldi'', the
unmarked suffix ''-di'' indicates
past tense. 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 source. A few languages distinguish between secondhand and thirdhand information sources.
''Sensory'' evidentials can often by 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
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 like a direct quotation). An example of a reportative from
Shipibo (''-ronki''):
: ''Aronkiai.''
: a-'ronki'-ai
: do-'
REPRT'-
INCOMPL
: "It is said that she will do it." / "She says that she will do it."

Typology of evidentiality systems
The following is a brief survey of evidential systems found in the languages of the world as identified in Aikhenvald (2003). 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.
2-term systems:
★ A1. witness, nonwitness (e.g.,
Jarawara,
Yukaghir languages,
Mỹky,
Godoberi,
Kalasha-mun,
Khowar,
Yanam)
★ A2. nonfirsthand, everything else (e.g.,
Abkhaz,
Mansi,
Khanty,
Netes,
Enets,
Selkup,
Northeast Caucasian languages)
★ A3. reported, everything else (e.g.,
Enga,
Tauya,
Lezgian,
Kham,
Estonian,
Livonian,
Tibeto-Burman languages, several
South American languages)
3-term systems:
★ B1. visual sensory, inferential, reportative (e.g.,
Aymara,
Shastan languages,
Qiang languages,
Maidu,
Quechuan languages, Northern
Embera languages)
★ B2. visual sensory, nonvisual sensory, inferential (e.g.,
Washo)
★ B3. nonvisual sensory, inferential, reportative (e.g.,
Retuarã,
Northern Pomo)
4-term systems:
★ C1. visual sensory, nonvisual sensory, inferential, reportative (e.g.,
Tariana,
Xamatauteri,
Eastern Pomo, East
Tucanoan languages)
★ C2. visual sensory, inferential #1, inferential #2, reportative (e.g.,
Tsafiki,
Pawnee)
★ C3. nonvisual sensory, inferential #1, inferential #2, reportative (e.g.,
Wintu)
★ C4. visual sensory, inferential, reportative #1, reportative #2 (e.g.,
Southeastern Tepehuan)
5+ term systems:
★ visual sensory, nonvisual sensory, inferential, reportative, assumed (e.g.,
Tuyuca,
Tucano)
★ witness, inferential, reportative, assumed, "internal support" (e.g.,
Nambiquara languages)
★ visual sensory, nonvisual sensory, inferential, reported, heard from known source, direct participation (e.g.,
Fasu)
★ nonvisual sensory, inferential #1, inferential #2, inferential #3, reportative (e.g.,
Western Apache)
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 where the post-verbal particle '' primarily functions as a mirative but also has a secondary function as an inferential evidential. This phenomenon of evidentials developing secondary functions or of other grammatical elements (e.g. miratives,
modal verbs) developing evidential functions is fairly widespread. The following types of mixed systems have been reported:
:
★ evidentiality with mirativity
:
★ evidentiality with
tense-
aspect
:
★ evidentiality with
modality ''(this is discussed in the next section below)''
In addition to the interactions with tense, modality, and mirativity, the usage of evidentials in some languages may also depend on the
clause type,
discourse structure, and/or linguistic
genre.
However, despite the intersection of evidentiality systems with other
semantic or
pragmatic 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
demonstratives 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,
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 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.
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''.
History of the concept
The term ''evidentiality'' was first used by
Franz Boas, later expanded to refer to
Balkan Slavic by
Roman Jakobson in 1957 (Jacobsen 1986:4; Jakobson 1990).
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).
