the lexical features of a language. The work is based upon the hypothesis that whenever two words are semantically dissimilar, this difference will manifest itself in the syntax via lexical distribution (in a sense, playing out the notion of distributional analysis [Harris 51]).

But while meaning specifies the core of a word class, it does not specify precisely what can and cannot be a member of a class. For instance, furniture is a mass noun in.
