Unitary Grammatical Function Hypothesis


The Unitary Grammatical Function Hypothesis claims that the same functions which appear in syntax (inflectional morphology) also determine the functional L-derivations. This is accomplished by investing deep structures with these functions before lexical insertion, then allowing both L-derivation and I-derivation to operate on them, as described in section 6 of the main text. LMBM assumes that a deep, categorial component is inevitable and that it is not a strictly syntactic component but rather a general grammatical component which feeds both the lexicon and syntax. Details are available in chapter 13 of Beard (1995).
