Se Arrepender vs. Lamentar: Regret Your Choice or Feel Sorry About an Event
Use se arrepender for regret about a choice
Arrepender-se commonly concerns looking back on your own choice and wishing you had acted differently. In Brazilian conversation, eu me arrependo and eu me arrependi are useful patterns. The pronoun changes with the subject: você se arrependeu, nós nos arrependemos. The feeling does not automatically tell you whether the choice can be undone; add that information if it matters to the discussion.
Me arrependi de ter comprado tão rápido.
I regretted buying it so quickly.
Ela se arrependeu da decisão.
She regretted the decision.
Keep de with the thing regretted
De connects se arrepender to a noun or an infinitive. It may contract with an article: de a decisão becomes da decisão. With a completed earlier action, de ter feito makes the sequence explicit. Do not force English regret doing directly onto the Portuguese verb without its usual connection. Learning one complete phrase, such as me arrependo de ter dito isso, keeps the relationship audible.
Me arrependo de ter dito isso.
I regret having said that.
Use lamentar for sorrow or regret about a situation
Lamentar can express sadness or regret over an event, including something you did not choose or cause. It commonly takes a noun or a clause. Lamento o cancelamento expresses regret about the cancellation, but it does not identify you as responsible for canceling. The expression can sound more formal than que pena in a casual chat, so choose the tone for the relationship.
Lamento o cancelamento da visita.
I am sorry about the cancellation of the visit.
Do not confuse feeling sorry with an apology
Lamento can appear in an apology, but the verb alone does not always mean admitting fault. Someone might lament a friend's missed opportunity without having caused it. If you need to apologize for your own action, name it and use a clear apology such as peço desculpas. If you only want to express sympathy, avoid adding a responsibility claim that the situation does not support.
Lamento o que aconteceu com você.
I am sorry about what happened to you.
Turn regret into a specific next step
When discussing a personal choice, you can explain what you would do differently next time. This makes the sentence more useful than a vague statement of bad feelings. With lamentar, you might instead offer support or acknowledge the disappointing news. Keep the choice and its consequence distinct: regretting how you spoke does not necessarily mean withdrawing every point you were trying to make.
Me arrependi do tom, mas ainda quero conversar sobre o problema.
I regretted my tone, but I still want to discuss the problem.
