Ido/Questions

To form questions that elicit yes/no reponses, place the particle "ka" or "kad" at the beginning of a sentence. Ka Sean iris a la skolo? Did Sean go to school? Kad el perdis la pekunio? Did she lose the money? Simple questions may be formed by placing "Ka" in front of a noun without a verb. Ka Michelle? can mean "Is it Michelle?" or "Do you mean Michelle?", depending on the context. If there is a word like who, what, where, etc., ka/kad is not used: Ube vu habitas? Where do you live? Quo es filozofio? What is philosophy? Quon vu timas? What do you fear? Qua es la prezidanto? Who is the president? Quante vu evas? How old are you?
