摘要：Structures consisting of a copula/linking verb go and an adjective phrase functioning as a resultaive subject complement (e.g. go purple) have not merited much space either in comprehensive descriptive works on English grammar or in some more theoretical studies cast within certain grammatical frameworks. A closer look at this construction reveals, however, that it raises a number of questions for syntactic theories. Most conspicuously, it invites us to consider the problem of the productivity of syntactic phenomena. It is argued here that a prototype-based, construction-centred account rather than a rule-and-principle-orientated one can answer these questions in a more satisfying manner.
