Truth is the most fundamental of all questions of appropriateness in language. Communication presupposes non-concealment between interlocutors, which logically excludes all forms of deception, not merely propositional lies. The lie, broadly conceived, is therefore a proper object of study for linguists, and a necessary one at a time when lying is cultivated as an art. As members of society, we have an obligation to contribute our skills in this as much as in other ways. Happily, a number of linguists have begun to respond by investigating the lies implicit in presuppositions, deletions, indirections, and loaded and jargonesque elements in the lexicon.
Dwight Bolinger (Sat,) studied this question.
