本文探討客家話的疑問句，分為四種：疑問語助詞問句、選擇問句、正反問句及疑問詞問句。此外，本文還討論了疑問句的焦點與答句的語助詞，共六個主題。結論是：這四種疑問句各有交之處，如選擇問句與疑問詞問句之共同處，在於兩者都以no為語助詞，且兩者回答都不同「是不是」之類的助動詞引導，而直接講出所選的標的答案。疑問語助詞及正反問句也有共同之處，兩者其實本質相同，因為有些客家語的疑問詞，源自於正反句之最後的否定詞。最後是答句的語助詞，與問句的語助詞一樣，它們都能在語用的層次上，表現答話者的各種不同的語氣與態度。

　　　　　The essential goal of this article is to examine the Hakka interrogative sentences, which are classified into four categories, particle interrogatives, selective interrogatives, tag questions, and wh-questions. In addition, we also discuss the focus of interrogatives and particles for replying. The conclusion is that while these four types of interrogatives are different from each other, there is some overlapping in nature. Finally, in replying sentences, the particles also show differences in pragmatics.
