Evidentiality

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 if so, what kind. An evidential (also verificational or validational) is the particular grammatical element (affix, clitic, or particle) that indicates evidentiality. Languages with only a single evidential have had terms such as mediative, médiatif, médiaphorique, and indirective used instead of evidential. Evidential is a meaning of nature and statement that is whether evidence exists for the statement and what kind of evidence exists.

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 (Spanish: deber de, Dutch: zouden, Danish: skulle, German: sollen) or other lexical words (adverbials, English: reportedly) or phrases (English: it seems to me). 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. Alexandra 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. A first preliminary study on evidentiality in sign language has been conducted by Laura Mazzoni on Italian Sign Language (LIS). 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, Japanese has inferential evidentials and reportive markers that are realized as suffixes on a variety of mainly verbal predicates, and as grammaticalized nouns. In another example, Eastern Pomo has four evidential suffixes that are added to verbs: -ink’e (nonvisual sensory), -ine (inferential), -·le (hearsay), and -ya (direct knowledge). 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; a person who makes a false statement qualified as a personally observed fact will probably be considered to have lied.
