 The considerations suggest that ‘in’ is ambiguous, but perhaps it is univocal with a very sense general meaning that involves containment of an appropriate sort and different objects require different sorts of appropriate containment. Telling between these two possibilities is difficult. An even harder case of lexical ambiguity involves the putative ambiguity in ‘any’ between the reading as a universal quantifier and a ‘free choice’ item. (see Dayal 2004)
