e-lesson

If British people do not hear or understand what is said, they may say Sorry? (GB), What? (informal), (I beg your) pardon? or Pardon me? (US).
Examples:
“Mike’s on the phone.” “Sorry?” “I said Mike’s on the phone.”
“You’re going deaf.” “I beg your pardon?”

Informally, especially in American English, they may use the phrase Come again?
