 Donnellan suggested that Russell’s quantificational account of definite descriptions might capture attributive uses, but that it does not work for referential uses. In effect, we might take Donnellan as saying that in some cases descriptions are Russellian and in some cases they are Strawsonian. Perhaps we could even say that the definite determiner ‘the’ is ambiguous between these two cases (it is not clear whether Donnellan himself intended to endorse a lexical ambiguity of this sort).
