Cách sử dụng
The expression "what, where, who, why, etc. the devil…" is commonly used when someone is surprised, confused or frustrated about something. For example, "What the devil is going on here?" or "Why the devil did you do that?". It is a way of expressing strong emotion and is often used informally in spoken language. However, it is important to note that the word "devil" is considered a strong or even offensive word in some contexts, so it may not always be appropriate to use in formal settings.
