Common mistakes

Avoid these common mistakes

Wrong Who are you?
Correct May I ask who’s calling?

"Who are you?" sounds too abrupt on the phone. In business phone English, it is better to use the polite formula "May I ask who's calling?"

Wrong Say again
Correct Could you repeat that, please?

"Say again" sounds too short and slightly rude for a work call. It is better to use a full polite request for repetition.
