S1 conventionally implicates S2 and S2 is false, then S1 is misworded, even if

A further type of "pragmatic presupposition" not already mentioned here
might be called "illocutionary implication": The performing of a speech act
in some sense implies the satisfaction of its distinctive felicity conditions.
For example, my promising to return your champagne glasses implies that
I intend to return them, and does so noncancelably (I cannot add, " . . . but
don't get me wrong; I have no intention of returning them"). To our penalty
catalogue, we might add that if someone utters S1, thereby performing a
speech act having S2 as a distinctive felicity condition, and S2 is false, then the
speech act is infelicitous in a distinctively illocutionary way.
