- In Commonwealth countries other than Canada, mad typically implies the insane or crazy sense more so than the angry sense.
- In the United States and Canada, the word mad refers to anger much more often than madness, but such usage is still considered informal by some speakers and labeled as such even in North American English by most UK dictionaries. This is due to an old campaign (since 1781 by amateur language pundits) to discredit the angry sense of the word that was more effective in the UK than in North America. Though not as old as the sense denoting insanity, the sense relating to anger is certainly very old (going back at least to the fourteenth century).
- On the other hand, if one is described as having "went mad" or "gone mad" in North America, this denotes insanity, and not anger. Meanwhile, if one "is mad at" something or has "been mad about" something, it is understood that they are angered rather than insane. In addition, such derivatives as "madness", "madman", "madhouse" and "madly" always denote insanity, irrespective of whether one is in the Commonwealth or in North America.
