A logical account of free-choice imperatives [pdf]Paper  abstract   bibtex   
Since Ross's observation that the instruction ``Post this letter'' does not entail ``Post this letter or burn it'', imperatives have constituted a challenge for the logician. Building on ideas from inquisitive semantics, we propose an account in which imperatives are regarded as partial specifications of a set of options. We show that this account avoids Ross's paradox and gives rise to a sensible notion of imperative entailment.
