lexical

Concerning the vocabulary, words, sentences or morphemes of a language.

So, it seems clear that the idiosyncratic restrictions relating to the range of complements which a Preposition does or does not permit are directly analo- gous to the parallel restrictions which hold in the case of Verbs. The restric- tions concerned are not categorial in nature (i.e. they are not associated with every single item belonging to a given category): on the contrary, they are lexical in nature (that is to say, they are properties of individual lexical items, so that different words belonging to the same category permit a different range of complements).
