The lexicalist position is that GF-rules both morphologically and syntactically take place in the lexicon and operate purely on the subcategorization frames and selectional specifications of the predicates involved ([Bresnan, J., 1982b, "The Mental Representation of Grammatical Relations", MIT Press, Cambridge]). The specific content of the arguments of the predicates will not be filled in until later, at the point of lexical insertion (combination).
