Domandare VS Chiedere

Hi,

Both Domandare and Chiedere mean "to ask", so which one should I use when I want to say "I asked him a question?"
I would like to know whether there is any distinct difference between these two verbs.

Thank you. 

Hi jingling,

The difference is there, but it's very subtle. You may find this question useful:

Your case is special, however. Domandare means to ask, and domanda means question. To avoid repetition (you'll notice these words are quite similar), Italian uses fare (to do): Gli ho fatto una domanda - I asked him a question. [lit. I did/made him a question]
Fare una domanda is a common collocation.

Hope this helps! :)
