Speaker authority can spring into existence via accommodation mechanisms: a speaker acts as if they had authority and they can end up obtaining it if nobody objects. Versions of this claim have been advanced by Rae Langton, Ishani Maitra, Maciej Witek, and others. In this paper, I shift the focus from speaker to hearer authority. I develop a three-staged argument, according to which (i) felicity conditions for illocution can be recast in presupposition terms; (ii) just as certain illocutions require speaker authority, there are also illocutions requiring hearer authority; (iii) accommodation may provide a way to confer authority to one’s audience, rather than gain it for oneself. Speakers sometimes act as if their hearer had authority, and the hearer can end up obtaining it solely by playing along. In closing, I pause on the potentially problematic interplay between informal authority conferral and social norms of female deference to men.
