Transformational grammar has attempted to outline the systematic nature of language structure while also stressing the creative aspect of language. Language is systematic in that speakers use a finite number of means to make up their messages, and yet it is creative in that there are an infinite number of individual different messages which are possible in any natural language. In natural languages, however, there is not a perfect one-to-one correspondence between possible messages—intended or perceived—and possible linguistic realizations, as there exists in conventional or artificial languages. Often it is found in natural languages that a single linguistic form may have two or more meanings. Homonymy, whether it is lexical or syntactic, is an important notion, not only because syntactic ambiguity plays a central role in linguistic theory, but also because its study gives us a better understanding of the systematics of language and of the way we attach meaning to linguistic representations. Hence, the importance of evaluating how speakers deal with syntactic ambiguity in their attempts to understand and to be understood.
