Using 'Lamentar que' + a Special Verb Form
When you say you regret that someone else does something, the verb that follows 'que' changes its ending. This special form is called the subjunctive. For example: 'Lamento que estés triste.' (I'm sorry that you are sad.)
Formal Regret vs. Everyday Apology
Mistake: “Using 'lamento' when you bump into someone on the street.”
Correction: For small, everyday apologies, use 'perdón' or 'lo siento'. Save 'lamento' for more serious regrets or formal situations, like saying 'I regret to inform you...'
