How to say "why do you?" in spanish?

Question

i know why is por que but what's do you? thanks =]

Answer 1

Por que haces

Answer 2

In Spanish they don't use an auxiliary verb to form questions, so the "do you" in that question is not translatable.

"Por qué haces" would actually mean "Why do you do?"

You should not translate the "do" that we use in English to form a question as "hacer" in Spanish--that's a big mistake.

So, you need to know exactly what you're asking in order to ask the question.

For example:

--Why do you need money?

--Por qué necesitas dinero? (lit. word for word: "why (you) need money?")
