This one made me think about the difference between "pedir" and "perguntar". It seems that "perguntar" is to ask a question and "pedir" is to ask for something.
you're right. Perguntar is related to question (for "to ask a question" we say "fazer uma pergunta")and "pedir" to ask for things.
I always think of it as if "pedir" is "to request" and "perguntar" is "to ask", but then I guess these two are pretty close in meaning in English anyway so that may not help as much as your distinction.
