Demander is a very common word with many uses, but the basic equivalent in English is ask for. For example:
Kevin is asking his sister for a piece of paper. -- Kevin demande une feuille de papier à sa sœur. (Notice that the person being asked is the indirect object, and the thing being asked for is the direct object.)
Another common usage is in the reflexive (se demander), which literally means to ask oneself but is often better translated as to wonder.
Je me demande pourquoi il est là . -- I wonder why he/it is here/there.
demander des
je commence à me demander: I begin to wonder, I begin to ask myself cela signifie d'être ... : that means to be ...
The English translation for the French verb 'se demander' is 'to wonder' or 'to ask oneself'.
Elle doit se demander
Je peux te demander ton prénom : can I ask you your firstname?
demander means to ask in French and 'une question' is 'a question', but the phrase should be 'poser une question'. You may 'demander une réponse' (ask for an answer), but not a question.
Wonderful in French is merveilleux/merveilleuse
to ask is 'demander' in French.I asked him > je lui ai demandé
je n'aurais pas pu demander mieux
Je suis trop demander, droit.
