This paper is a study of Japanese and Sinhala wh-questions, both of which employ a special particle called a Q-particle, ka in Japanese and də in Sinhala, forming QP. A Q-particle is normally base-generated adjacent to a wh-phrase or at the edge of an island when a wh-phrase is inside. However, under very restricted circumstances, a Q-particle can merge with TP, and the whole TP can be pied-piped to spec of CP. An information-seeking wh-question normally represents a set of unvalued propositions (i.e. Hamblin set); however, we claim there are cases in which a set of true propositions (i.e. Karttunen set) can be the meaning of an information-seeking wh-question, and this happens when TP pied-piping is applied. Each circumstance in which such pied-piping is possible is carefully analyzed.

僧伽罗语和日语Wh疑问句中的隐蔽管道的语法，语义和语用

本文是日本和僧伽罗语的研究WH -questions，这两者都采用一种特殊的粒子称为Q-颗粒，KA在日本和də僧伽罗语，形成QP。A Q-粒子通常为碱生成的邻近WH用作名词或在岛的边缘时一个WH用作名词是内部。但是，在非常有限的情况下，Q粒子可以与TP合并，并且可以将整个TP粘贴到CP规范中。一种信息寻求WH -question通常表示一组未赋值命题（即汉布林集）; 然而，我们要求有其中一组真命题（即Karttunen套）可以是寻求信息的意思的情况下WH问题，并且在应用TP管道连接时会发生这种情况。仔细分析了可能出现此类管道的每种情况。
