To make an inversion in french?
When we have the question words such as où. comment, porquoi, qu'est-ce que, qui, etc, do we always have to use the inversion. For example, where are you? Où es-tu? And do we always put the dash between the subject and the predicate in the inversion? What are you doing? Qu'est ce que tu fais? Or fais-tu? Is it possible to ask Quoi fais-tu?
