The syntax of wh-questions has been described and analyzed for several sign languages to date. The general strategy has consisted in determining the range of possible interrogative structures that feature wh-signs, with particular emphasis on the directionality of wh-movement and its syntactic representation. Limited attention, though, has been given to the contextual factors that license the use of syntactically marked wh-structures, basically treating all varieties as more or less equivalent. In this paper, we focus on Catalan Sign Language (LSC) and we address the need to distinguish between canonical varieties of wh-questions (purely information-seeking, thus context-neutral) and non-canonical ones (dependent on particular pragmatic contexts), taking into account both the pragmatic and syntactic properties of these structures. We thus offer a preliminary account of non-canonical wh-questions in LSC and show that marked syntax flags them. We take into consideration in situ content questions occurring in contexts leading to an echo interrogative and triggering a reaction of concern, as well as wh-structures with doubling of the wh-element licensed by a context of concern.
