This paper provides a detailed description of reduced embedded questions in Uyghur and proposes to derive them from two sources: cleft constructions and pseudo-sluiced clauses. I argue that reduced questions with non-case-marked remnant interrogative phrases can be derived from either source. Further, I argue that reduced questions with remnant phrases followed by case markers and postpositions should be derived from cleft constructions. The pseudo-sluicing analysis is supported by the appearance of a copula and pronominal subjects in those reduced questions and by the fact that reduced questions can be pragmatically controlled. Further, the cleft analysis is supported by the appearance of a copula and case- and postposition-marked pivots in cleft sentences and by subject drop, which is independently allowed in the language.
