Lexical polysemy and the lexicon-syntax interface

In this paper we start from the controversial distinction between variants and invariants of content - in the framework of the European functional structuralism-, distinction unresolved in many cases in the analysis of the phenomenon of lexical polysemy, to connect this problem, in the field of the interrelationship between lexicon and syntax, with the analysis: 1) of certain constructions with the verb do to check if it has not produced or re-categorization of this verb and 2) of certain tests syntactic-semantic behavior with verbs of state and achievement that would lead us to the possibility that also accept other readings. In both types of studies the essential question to be solved is not, then, whether we are dealing variants or invariants of content, although the phenomenon of lexical polysemy is always present. Based on the theoretical assumptions of the European functional structuralism, we incorporate other of the compositional semantics and some cognitivists orientations.
