“…The body of work on the semantics of wh-questions, sparked by classic works like Hamblin 1973, Karttunen 1977, and Groenendijk & Stokhof 1982, 1984, is substantial, yet most of this literature focuses narrowly on questions about individuals or degrees. In particular, discussion relating to the semantics of howand why-questions -questions about modes and reasons, as we will say -has remained sporadic (e.g., Oshima 2007;Abrusán 2014;Saebø 2016). 1 The reasons for this limitation presumably include the uncertainty regarding the contents of the propositions that constitute answers to howand why-questions, which limits the utility of these questions in the investigation of certain general issues in the study of questions, most notably the semantics of question embedding.…”
