Abstract
This chapter investigates interrogative sentences found in Romance languages and their varieties and discusses structural analyses for polar and constituent questions in main and embedded contexts. It also addresses topics such as basic constituent order in interrogatives, especially the order of subjects with respect to verbs, wh-movement and the licensing of wh-in situ in simple and multiple interrogative sentences. This chapter will also discuss est-ce que-questions in French and a similar type in Portuguese as well as complementizer questions in Italo-Romance varieties. The data are mostly from spoken and written corpora of French, Italian, Spanish and Portuguese, but we will also discuss other languages and varieties.
