Evidentiality
linguistic indication of the nature of evidence for a given statement, often using modal verbs
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.
Evidentiality may be direct or indirect: direct evidentials are used to describe information directly perceived by the speaker through vision as well as other sensory experiences while indirect evidentials consist of the other grammatical markers for evidence such as quotatives and inferentials.
Introduction
All languages have some means of specifying the source of information. European languages (such as Germanic and Romance languages) often use 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. 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.
Alexandra Aikhenvald (2004) reports that about a quarter of the world's languages have some type of grammatical evidentiality.
The public source identifies “Evidentiality” as linguistic indication of the nature of evidence for a given statement, often using modal verbs. This brief keeps that definition visible, then builds a research path around Evidentiality, linguistic and indication.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Evidentiality”, the useful work is to connect “linguistic indication of the nature of evidence for a given statement, often using modal verbs” to the records capable of establishing context and consequence.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 22, 2026. The linked authority identifier is Q12223979. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2004.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
