摘要：This paper discusses the notion of grammatical well-formedness in the light of certain optimality approaches to syntactic phenomena (e.g.,Pesetsky 1998; Grimshaw 1997; Grimshaw & Samek-Lodovici 1995; Costa 1998). Such approaches adhere to assumptions that lead to the following theorem: a linguistic representation may violate a rammatical constraint and still be well-formed if and only if all other alternative candidates also violate some grammatical constraint. The point the paper makes is: if well-formedness is the theoretical correlate of full acceptability, this theorem is in trouble. The arguments come from the analysis of two marked constructions of English: logophoric reflexives (Reinhart & Reuland, 1993) and peculiar passives (Davison, 1980). The paper argues that these phenomena arise as a result of a Gricean implicature triggered by violations of grammatical constraints, and that conversational implicatures cannot be characterized as the result of competition among grammatical constraints.
