Deliberate ambiguity as motivated strategy

In this paper, we investigate ambiguity in language use that is intended by the speaker. Our overall argument is that, as a general feature of language resulting from the indeterminacy of meaning at all levels of language, ambiguity can be taken advantage of in specific contexts for a host of purposes. Given that an ambiguous utterance has (at least) two possible meanings – A and B – there are two logical possibilities for a speaker in a deliberate ambiguity: to mean both A and B or to mean only A (or B). However, a closer examination of the literature and available data reveal a far more complicated picture: there are more strategies under either of these possibilities, each of which closely interacts with the context and is motivated by the speaker's purpose of communication in that context. The treatment of deliberate ambiguity in the present study is thus more coherent theoretically and more comprehensive in coverage than what is found in the sizable literature on the subject.
