In 1977, Kempson published Semantic Theory, which discusses the concept of entailment in linguistics. A proposition (P) is entailed by another (Q) if P is true when Q is true and Q is false when P is false, but Q is not strictly defined if P is true.[3] She was awarded a Fellow of the British Academy in 1989.[4] She has made contributions to the theoretical framework of Dynamic syntax.[5]
