"To regret about" is wrong to regret something = to have a regret/regrets about something

Good question. Both can be used depending on your sentence structure. You regret things that you have done or you can HAVE regrets about something. So: You can REGRET IT. or You can HAVE REGRETS ABOUT it. Hope that helps. Good Luck!

If you use 'regret' as a verb, you don't use about. You have two options 1. regret+noun 2. regret+verb+ing 1. I regret my mistake 2. I regret that decision 1. I regret buying the house 2. I regret saying that to her

Hi Olga, You do not need to use "about" with "regret". Examples: If you use it as a verb, you may write: I regret telling you my secret. I regret my actions. In these sentences, "regret" means the ACTION of feeling sorry and wishing something was done differently. If you use it as a noun, you may write: I would like to express my regret. Life is full of regrets. In these sentences, "regret" means a state of BEING sorry that something was not done properly. Hope this helps. Cheers, Lance
