An interesting development in the last decade or so has been the increasing use that theoretical linguists have made of the notion ‘head’ – or rather, in order not to beg the question, of notions to which they have given the name ‘head’. The term has been around for a long time in linguistics, of course – for example Bloomfield uses it in relation to endocentric constructions (1933: 195), where the head is the daughter constituent which has the same distribution as the mother. Before that, Sweet had used ‘head-word’ to refer to any word to which another is subordinate (1891: 16, quoted in Matthews, 1981: 165). However, theoretical linguists made very little use of the term, or of the constellation of associated concepts, until quite recently. Its present status is due largely to work on X-bar syntax dating from Chomsky (1970), and especially to its recent manifestation in Generalised Phrase Structure Grammar (Gazdar & Pullum, 1981; Gazdar et al., 1985)–and even more so in the ‘head-driven’ variant of this (Pollard, 1985). But the improved status of ‘head’ is also due to some extent to the renewed interest in dependency grammar (Anderson, 1971, 1977; Matthews, 1981; Atkinson, et al, 1982; Hudson, 1984; Nichols, 1986). All these treatments agree not only in using the term ‘head’, but also in using it to refer to the element in some construction to which all the other parts of that construction are (in some sense) subordinate.
