The phrasal verb "look after" is predominantly used in informal speech, though it can appear in more casual formal writing or dialogue as well. It generally means to take care of someone or something, ensuring that they are safe or well-maintained, and is often used in contexts involving children, pets, plants, or general responsibilities, such as "Can you look after my dog while I'm on vacation?" or "She looks after her younger siblings." The verb encompasses both physical protection and emotional or supervisory care. It conveys a sense of responsibility and guardianship. In more formal contexts, phrases like "manage" or "tend to" may be used as substitutes for "look after."
