return it back

Wrong, wrong, wrong. I seriously doubt that any properly educated native speaker of English would use such a lame locution as "return it back."

One might write: ". . . you can return it to me." One might write: " . . . you can give it back to me." But no one who is normally articulate in English would write: " . . . return it back . . ."

Thanks, Setanta.

Not to mention that "return" means "to give back", so you wouldn't repeat yourself that way - it's redundant.
