Abstract The Italian pair *il luo libro vs. il suo libro (‘the his/her book’) that is typical of Romance lends itself to an account of the first in terms of constraints also seen in the syntax of compounding, and to an account of the second that links its s-, despite initial appearances, to what we think of as Romance reflexive s-. We might informally call this pair an instance of suppletion, as long as we recognize that calling it suppletion falls short of an account.

理解浪漫代词所有格的明显补充

摘要意大利文对* il luo libro与il suo libro（“他/她的书”）是典型的罗曼史，这有助于使他首先考虑到在复合句法中所看到的约束方面，尽管有最初的外观，但将其s-与我们认为是浪漫反身s-关联的第二个原因的说明。只要我们认识到称其为补充不足，我们就可以非正式地称这对为补充。
