  • Usage notes

    While within the United States and Canada, the word mad'' ''does'' generally imply ''anger'' rather than insanity, such usage is still considered informal. Furthermore, if one is described as having "gone mad" or "went mad", this will unquestionably be taken as denoting ''insanity''''', and not anger. Meanwhile, if one "is mad at" something or has "been mad about" something, it will be assumed that they are '''''angered'' rather than insane. In addition, if the word is understood as being used literally, it will most likely be taken as meaning "insane". Also, in addition to the former, such derivatives as "madness", "madman", "madhouse" and "madly" ''purely denote insanity, irrespective of whether one is in the Commonwealth or in the United States. Lastly, within Commonwealth countries other than Canada, mad'' typically implies the ''insane'' or ''crazy'' sense more so than the ''angry sense.
