Avoid saying “What?” when asking someone to repeat something.
It sounds quite rude because it’s too direct.
Use these alternatives that sound much more polite.
👩🎓 Come again?
👩🎓 Sorry, I didn’t (quite) catch that?
👩🎓 Pardon? / I beg your pardon?
👩🎓 Sorry, can you say that again, please?
👩🎓 Say again?
There are even more phrases that you can use instead of “What”. Which other ways do you use?
