Whean?

There is a shortage of good question words. Who, what, where, when, why and how, are limiting and often require additional words to formulate a precise question. So I try to come up with my own. One of my recent favorites is "Whean"? As in "What do you mean?" which comes in handy when you ask for clarification as often as I do. Does anyone know of any question words in other langauges that are not synonymous with the English ones mentioned above?
