I beg your pardon
1. I apologize for what I just did or said. Oh, I beg your pardon. I wasn't looking where I was going.
2. What did you just say? Could you please repeat that? I beg your pardon, I couldn't quite hear you.
3. An expression or exclamation of indignation or incredulous disbelief. A: "I'm afraid we're going to have to cut your funding, effective immediately." B: "I beg your pardon? Who on earth decided that?"
4. Could you please give me your attention. I beg your pardon, everyone, but I'd like to get tonight's proceedings underway.
5. I believe you are mistaken or incorrect; I beg to differ; I don't agree with you on that. I beg your pardon, but I believe you'll find that our school is actually one of the best in the state.
