respond back vs respond, reply : Common Errors in English

About respond back vs respond, reply

It’s possible that some people think they have to write “respond back” to distinguish a reply from other kinds of responses, like groaning and cursing, or chucking a request in the wastebasket; but most of the time the context makes perfectly clear that “respond” means “answer” and the “back” is redundant. Or you can just say “reply.”
