Learn French: Qui, moi ?

Je (I) is a subject pronoun, which means it needs to be attached to a verb (like in je mange). When a pronoun stands completely alone without a verb, French uses stressed pronouns like moi.

How do you pronounce qui? Does it sound like 'kwee'?

No, it sounds exactly like the English word 'key'. The u in qui is silent.

Why is there a space before the question mark?

In French writing, you must always put a space before two-part punctuation marks, which includes question marks, exclamation points, colons, and semicolons.

How would I say 'Who, him?' or 'Who, her?' using this same pattern?

You just swap moi for the correct stressed pronoun! You would say Qui, lui ? for 'Who, him?' and Qui, elle ? for 'Who, her?'.
