In this paper, we develop a new typology of multiple wh-questions with coordinated wh-pronouns. We motivate the existence of three distinct structures for such questions: one mono-clausal and two bi-clausal. We use four kinds of diagnostics to determine which of the three structures is available in a particular language: the availability of both multiple wh-questions and wh-questions with coordinated wh-pronouns, coordination of two argument wh-phrases, transitivity restrictions and superiority effects.
