Cách sử dụng
The term 'theoretical' is used to describe something that is based on ideas, concepts, and reasoning rather than practical experience. It is often used in academic or scientific contexts to describe a study or concept that has not yet been proven or tested in real-life situations. For example, theoretical physics involves exploring and developing ideas about the nature of the universe, without necessarily conducting experiments to prove them. In everyday language, 'theoretical' is often used to describe something that is hypothetical or speculative, rather than factual.
