Cách sử dụng
The phrase "on topic" is used when we want to talk about something that is relevant or related to the subject being discussed. We use it to describe conversations, presentations or discussions that stay focused on the topic at hand. For example, if a group of people are talking about a specific type of food, then talking about something unrelated like sports would be considered "off topic". In English, we often use this phrase to make sure that we are staying on track and not getting sidetracked.
