Cách sử dụng
The expression "a train of thought" refers to a series or sequence of connected ideas or thoughts that occur one after the other in a person's mind, like cars following one another on a train track. This expression is usually used when someone is thinking out loud or trying to express their thoughts in words to someone else, and they want to convey that their ideas are connected and forming a particular line of thinking. For example, if someone says "Let me finish my train of thought," they mean that they need to continue talking about their idea without interruption so they can fully explain their thinking.
