As is well known, all relative clauses in Modern Chinese are marked with de. Compared with Modern Chinese, Archaic Chinese seems to have a richer encoding for relative clauses. It has three possible relative markers: zhe, zhi and suo. In this article, we will approach to Archaic Chinese relatives from the perspective of formal syntax. We will argue that zhe is a subject relative pronoun and suo a VP internal relative pronoun, and that zhe– and suo– relatives are derived from the A’-movement of the relevant relative pronoun to the peripheral position, creating an operator-variable relation at LF. Simultaneously, we will use Cecchetto and Donati’s labeling theory to account for a peculiar phenomenon that the same relative pronoun can form both headless and headed relatives. We will further argue that the relative marker zhi, as English that,is an invariant relativizer occupying the C position, and that zhi-relatives involve null operator movement. That is to say, like English type of languages, Archaic Chinese actually involves two separate relativizing strategies: through a relative pronoun or a null operator. The article also contributes to the debate on the analysis of relatives: data from Archaic Chinese favors an Adjunction Analysis to the Raising Analysis (or Complementation Analysis) à la Kayne.
