Pro-drop in interrogatives across older Germanic and Romance languages

This chapter investigates the mechanisms of null subject licensing in direct interrogatives, an environment which is generally neglected in investigation into null subjects, using data from a range of early Romance and Germanic languages considered to be asymmetric pro-drop languages, i.e. languages in which null subjects are favoured in main clauses. We find that there is subtle variation between the languages in question, but that two factors in particular – interrogative type and person – are crucial in conditioning this variation, and we sketch analyses based on the differential availability of Agree relations with left-peripheral elements. Therefore, null subjects in main interrogative clauses are licensed in two slightly different manners in the two language families – a fact which we show follows from differences in the structure of their left periphery and in agreement morphology.publishe
