 note = {P(論文), Under the framework of Government and Binding Theory, empty categories (ECs) are discussed in terms of how they are licensed and how they are interpreted (identified) and at least four types have been identified; PRO, NP-trace (pure anaphor), pro, and wh-trace (variable), the latter two of which are in a 'governed' position. In this paper, I will claim that certain 'governed' subject ECs, such as the subject of imperatives and the 1st person subject in Japanese, are licensed at the CP level via AGREE(ment), provided that the CP system encodes features (or heads) that make the relevant subject EC sufficiently identifiable. I will then claim that PRO may be licensed in a similar way, adopting the spirit of Borer's (1989) anaphoric AGR analysis.},
