ABSTRACT
The Lexical Hypothesis is about the organization of the grammar into modules. It suggests that the system of words in a language is independent of the system of phrases in a language in a particular way. It is independent of it, but communicates with it through a narrow channel—the “top-level” properties of words. The system of words determines what the words of a language are, and what their properties are. The system of phrases determines how words form phrases, based on the properties of words.
