ABSTRACT
At first sight, this may not look like a very ambitious goal. Compared to those relations of meaning in which Superstructuralists deal, grammatical relations may seem somewhat incidental to the main business of language. We are not in the habit of placing any great importance upon parts of speech. No doubt every word has to have a grammatical role; there is no known human language in which words are not grammatically categorized. But we tend to think of such categories as tacked on and secondary-certainly not on a par with a word’s meaning.
