| 概要 |
In this paper, I address the issue of the well-known developmental stage: Children who acquire English as a native language produce negative wh-questions without Subject-Auxiliary Inversion (SAI) (e.g...., Why we can't find the right one?). Given the WH-Criterion is regarded as one of the principles in UG, two questions arise on children's utterances: why do children produce them and how can the structure satisfy the WH-Criterion? I propose that category labels of functional categories are underspecified at the stage of language development. Specifically, children project underspecified functional phrase (FP) which has the properties of both CP and IP. The two questions can be answered by assuming, (i) the element with the only one feature concerning the sentence type such as [+WH] can occur in the head of FP (F0) and (ii) negative sentence is one of the sentence types at the stage of language development.続きを見る
