The Vietnamese word "cụ thể" means "concrete" or "specific." It is used to describe something that is clear, definite, and tangible, as opposed to being vague or abstract.
In more formal or academic contexts, "cụ thể" can refer to the process of making abstract ideas more tangible or understandable. For instance, you might say, "Chúng ta cần cụ thể hóa các khái niệm này." (We need to concretize these concepts.)
While "cụ thể" mainly means "concrete" or "specific," it can also be used in a broader sense to denote clarity or precision in communication.
