Saying sorry

For small mistakes like saying someone’s name wrong

Whoops! Sorry!

Oh, sorry.

My fault.

I beg your pardon.

For a more serious mistake

Sorry.

I’m sorry.

I am so sorry for …

I am really sorry.

Sorry about that.

I apologize for …

If you give incorrect information or cause a problem with communication

My mistake.

I was wrong on that.

My apologies.

I had that wrong.

If you make a formal apology

I want to apologize for …

I’d like to apologize.

I wanted to tell you I’m sorry.

I hope you can forgive me.

That was wrong of me.

If you write a formal apology

I sincerely apologize.

I take full responsibility.

… for my behaviour.

… for my actions.

If you say sorry, but you are not really apologizing

Excuse me.

Pardon me.
