Trope-a-Day: Language of Truth

Language of Truth: There is no first-class language of truth (that is more or less impossible), but Eldraeic was custom-designed to make speaking logical fallacies – by a variety of logics – bad mathematical statements, woeful imprecision, etc., etc., as difficult as possible if not downright ungrammatical, especially when spoken in formal registers.

While this does, as intended, make life more difficult for amateur liars, the general feeling is that even when professional liars (diplomats, say; see Will Not Tell A Lie) are called for, they really ought to be above that sort of cheap fast-talking anyway.
