Here, the novelty involved refers to the manufacture of new metaphors and new juxtapositions of words in a manner that is in some way felicitous and pleasing to the hearer or reader. It is this kind of novelty whose presence often mystifies the .student in a poetry lesson and whose absence exasperates the composition teacher. This characteristic operates at both the word level and the phrase or sentence level. Let us examine how this is true in both instances. The specification of the attributes of a concept is not a simple matter, and in fact, there are no known ways of generating such specifications in a completely adequate manner.
Similar difficulties beset the lexicographer's attempt to specify in full the attributes of a word.
One might think, at first, that this kind of fuzziness of the meaning of words is a disadvantage. Quite the contrary is true. Some constraints must operate. Syntax is an efficient device for indexicality. For instance, simple conceptualizations can be expressed by means of complex syntactic structures, but there are limits on the degree of complexity of conceptualization that can be expressed by means of simple syntactic structures.
