What is "veridicality"

n. 1 truth. 2 (context psychology philosophy English) The degree to which something, such as a knowledge structure, is veridical; the degree to which an experience, perception, or interpretation accurately represents reality.

In linguistics, veridicality is a semantic or grammatical assertion of the truth of an utterance. For example, the statement "Paul saw a snake" asserts the truthfulness of the claim, while "Paul did see a snake" is an even stronger assertion. Negation is veridical, though of opposite polarity, sometimes called antiveridical: "Paul didn't see a snake" asserts that the statement "Paul saw a snake" is false. In English, non-indicative moods are frequently used in a nonveridical sense: "Paul may have seen a snake" and "Paul would have seen a snake" do not assert that Paul actually saw a snake (and the second implies that he did not), though "Paul would indeed have seen a snake" is veridical, and some languages have separate veridical conditional moods for such cases.
