This article deals with imperative constant polarity tag questions (henceforth imperative CPTQs) such as Leave me alone, will you and Let's have another, shall we. We propose a typology of imperative CPTQs on the basis of a systematic study of data, correlating their distinct formal properties with different contextualized uses. Further developing McGregor's (1997) general approach to tag questions, we argue that the main subtypes of imperative CPTQs can be classified in terms of two interpersonal functions: illocutionary force and conduciveness. These two interpersonal dimensions form continua ranging from speaker-oriented to hearer-oriented meanings. The classification in terms of illocutionary force subsumes speaker-oriented command and request, speaker- and hearer-oriented proposal for joint action, and hearer-oriented advice and invitation/offer. The corresponding conduciveness cline involves mainly ‘softening’ at the speaker-oriented end, where the speaker's desire predominates, and ‘insisting’ at the hearer-oriented end, which focuses on the benefits to the hearer.
