Frequently Asked Questions
Why is 'arrepentirse' reflexive?
Think of it as the regret is being directed back at yourself. You are 'repenting yourself' of an action. That's why it always needs a pronoun like 'me', 'te', or 'se' to show who is feeling the regret.
Can I ever use 'lamentar' for my own actions?
Yes, but it's less common and has a different feel. 'Lamento haber llegado tarde' (I regret arriving late) is correct, but it sounds more formal, like you're apologizing for the inconvenience it caused. 'Me arrepiento de haber llegado tarde' sounds more personal, like you genuinely feel bad about your choice to be late.
Do I always need 'de' after 'arrepentirse'?
Yes, when you specify what you regret, you always use the structure 'arrepentirse de + [noun]' or 'arrepentirse de + [infinitive verb]'. For example, 'Me arrepiento de mi error' or 'Me arrepiento de haber mentido'.
