Abstract: Wh-questions belong to a common question type in Hefei dialect, and they have significant characteristics. The results of descriptive analysis show that the Hefei dialect wh-questions differ in the form of interrogative pronouns, which mainly comprise six types: asking people, things, time, place, number, reason, and mode. Different interrogative domains have different interrogative pronouns. In terms of pragmatics, in addition to the usual questioning function, wh-questions have three special functions: the "explanation" and "reference" functions of interrogative pronouns, the rhetorical function of interrogative pronouns, and the mixed use of question types. Semantically,interrogative pronouns, ending modal words and question tone will all affect the interrogative focus of wh-questions.

Key words: Hefei dialect, wh-questions, interrogative pronoun, focus
