Evidentiality is a grammatical mood that expresses the type of evidence on which the speaker bases a statement. Direct evidentials are used when the speaker has first-hand evidence that the incident occurred, such as visual, auditory, or other first-hand evidence; these three subtypes may or may not be distinguished, depending on the language. Indirect evidentials are used when the speaker is not a first-hand witness, but instead learns the information through inference (known as inferential evidential) or a second-hand source (quotative/reportative evidentials).
NoEvid: The language does not have a grammaticalized form to express evidentiality.
EvidAff: Evidentiality is marked by the use of clitics or affixes.
EvidParad: Evidentiality is a feature of the verbal paradigm.
EvidPart: Evidentiality is marked by the use of specific particles.
EvidModMf: Evidentiality is marked by the use of modal morphemes, such as modal affixes or modal auxiliaries.
EvidMix: Evidentiality is marked by the use of a combination of the strategies listed above.
 If this value applies to a language, it applies by default in the parameter Evidentiality.
 A clitic can attach to any word class.
 Usually a distinct verbal mood, evidentiality generally applies to the past tense, although it may also be used in other tenses. The distinction may also be partial; some tenses express definite evidentiality, while others are ambiguous in terms of evidentiality.
 Specific particles generally mark indirect rather than direct evidentiality, although some exceptions can be found, such as for direct visual evidentials in particular.
 These morphemes do not have to code evidentiality exclusively; in some languages, there is an overlap with the irrealis or subjunctive moods. The function(s) of the modal morpheme should be detailed in the commentary.
 For example, evidential particles and inflection may occur simultaneously. The combination should be detailed in the commentary.
