Learn French: Le projecteur est ici, branche-le-moi ! - The projector is here, plug it in for me!

In affirmative commands (telling someone to do something), the order of pronouns changes from normal sentences. The direct object (le, la, les) always comes first, followed by the indirect object (moi, toi, lui, nous, vous, leur). Since le is the direct object (the projector) and moi is the indirect object (for me), it has to be branche-le-moi.

Why do we use moi here instead of me?

When a pronoun is attached to the end of an affirmative command, the word me changes to its stressed form moi (and te changes to toi). You will also notice that all pronouns attached this way are connected to the verb and to each other with hyphens.

Why doesn't branche have an "s" at the end, since it's the "tu" form?

For verbs ending in "-er" (like brancher), the "tu" command form drops the final "s" in the present tense. So while you would say tu branches in a normal sentence, it becomes just branche ! as a command.

Could I say branche-le pour moi instead?
