Learn French: C'est pour moi ?

In French, whenever a pronoun comes directly after a preposition like pour (for), avec (with), or de (of/from), you must use a stressed pronoun. Moi is the stressed pronoun for 'I' or 'me'. You cannot say pour je or pour me.

C'est normally means 'It is'. How does it mean 'Is it' here?

In conversational French, the easiest and most common way to ask a question is simply to take a normal statement (C'est pour moi meaning 'It is for me') and let your voice go up at the end. You do not always need to use special question words or swap the order of the words.

If I want to ask 'Is it for him?', do I use il or le?

Neither! Since the pronoun comes after the preposition pour, you need the stressed pronoun for 'him', which is lui. The question would be C'est pour lui ?. For 'her', you would use the stressed pronoun elle, making it C'est pour elle ?.

Could I say 'Est-ce que c'est pour moi ?' instead?

Absolutely. Est-ce que c'est pour moi ? is perfectly correct and slightly more formal. However, native speakers often prefer the shorter, simpler version in casual everyday speech.
