Perspectives on Concealed Questions
Floris Roelofsen, Maria Aloni

Abstract:
This paper presents a novel theory of concealed questions (CQs). The
theory is the first to provide a unified and principled account of
definite, indefinite, and quantified CQs and CCQs (CQ-containing
CQs). It also explains Greenberg's (1977) observation and some related
facts.
