Word formation in generative grammar

In spite of the wide-spread recognition that morphology has a place in generative grammar, Aronoff's book is one of the few proposals of a theory of morphology within that framework, and is certainly the most extensive. Much of the book centers around traditional observations concerning morphology, particularly those of the American structuralists, and how they are to be handled and/or explained within a generative account. In fact, in some respects Aronoff's model appears to re-adopt earlier, pre-generative views; e.g., his proposed class of allomorphy rules (see below) is reminiscent of what were called morphophonemic rules in an earlier tradition. However, in important respects that will be pointed out below, Aronoff's claims represent a departure from traditional assumptions as well as from earlier generative accounts. -- from (Feb. 7, 2014).
