On some mysteries, asymmetries and derivation of potential de construction in Chinese

In this paper, some mysteries and asymmetries of the Chinese potential de construction are investigated. It is shown that a morphosytnactic approach is conducive to accounting for these puzzles. First we explore the possibility of taking de and its negative counterpart -bude as functional heads (cf. Tsai 2001; T. Wu 2004). It is proposed that bude could be a functional head with the negative potential meaning (i.e. impossible/impermissible). This could be evidenced by both empirical data and theoretical deduction. It is argued that bu in V–bu–R, which is distinct from the normal pre-verbal negative morpheme bu, is actually bude. This helps to explain why the negative potential meaning is involved in V–bu–R. Meanwhile, V–de/bude and V–de/bu–R are both assumed to be formed through Morphological Merger (cf. Marantz 1988; Embick & Noyer 2001, 2007, etc.). Meanwhile, we have discussed some asymmetries observed between V–de/bude and V–de/bu–R and some paradigmatic asymmetries between potential V–de construction and its negative potential V–bude construction. It is assumed that these syntactic asymmetries may be due to some morphological operations related to de and bude.
