A question asked when one answering the phone needs to put the caller on hold. Let me see if he's in his office—can you hold?
Could you hold?
and Can you hold?; Will you hold?Do you mind if I put your telephone call on hold? "Could you hold?" asked the operator. Sue: Hello. Acme Motors. Can you hold? Bob: I guess. Sue (after a while): Hello. Thank you for holding. Can I help you?
