I believe having regrets is a waste of time and energy, and that it’s best to learn from our past in order to move on. However, in everyday language we use the expressions, “should’ve/would’ve/could’ve” often to justify, reason, and explain a given situation, especially by adding the word “if.”
In French, “should have, would have, could have” is expressed by the past conditional tense: formed by using the conditional of the helping verbs “avoir” or être” + the past participle of the verb. It takes practice, so here’s some sentences to translate (and a beautiful song):
