Performative hypothesis

SEMANTICS: the hypothesis (proposed in Ross 1970), that every sentence is associated with an explicit illocutionary act, i.e. is derived from a deep structure containing a performative verb. EXAMPLE: sentence (ia) is derived from (ib), or perhaps (ic):

(i) a I'll write you next week
    b I claim I'll write you next week
    c I promise I'll write you next week
