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?
