An important question that arises with respect to the organization of the lexicon is what the best theoretical framework is for showing (a) how lexical items are related to one another and (b) how concepts are lexicalized, that is, expressed in words. In particular, is there an empirical difference between the claims of semantic field theory and semantic frames? If there is a difference, is one approach superior, or does each have advantages in handling information that the other does not? This chapter addresses these issues by examining proper names in English.
