Present indicative forms vary by dialect: eu comento, você comenta (or tu comentas in some varieties), ele comenta, nós comentamos, vocês comentam.

Usage: comentou is used to report a past act of commenting on a topic, document, post, or statement. Common constructions include: "Ele comentou o relatório," "Ela comentou no post," "O jornalista comentou a notícia." It can introduce direct speech: "Ele comentou: '...'," or indirect speech: "Ela comentou que chegaria tarde." The word is widely used in media, online platforms, and everyday conversation.
