usage note for mad
Mad meaning “enraged, angry” has been used since 1300, and this sense is a very common one. Because some teachers and usage critics insist that the only correct meaning of
mad is “mentally disturbed, insane,”
mad is often replaced by
angry in formal contexts:
The president is angry at Congress for overriding his veto.
historical usage of mad
The history of
mad is complicated both in form and in meaning. In form
mad goes back to Old English
gemǣd “troubled in mind, demented,” the past participle of an unrecorded verb
gemǣdan “to madden, make foolish,” a derivative of the adjective
gemād (also
mād ) “unreasoning, foolish, mad.”
The Old English forms are from the Germanic adjective gamaidaz “changed for the worse, abnormal.” The element maid- in gamaidaz is from Proto-Indo-European moi-, a variant of the root mei-, moi- “to change, exchange, go, move,” extended with a dental suffix ( -d in Germanic, -t elsewhere). The same suffixed variant moit- appears in Latin mūtāre “to change, exchange, give and receive in exchange.” Sicilian Greek (therefore likely to be influenced by Latin) has the noun moîtos “thanks, favor, reward,” which is possibly a borrowing from Old Latin moitus.
The progression of senses of mad starts with its original sense in Old English, “troubled in mind, demented.” The senses “rabid (dog),” “foolish or unwise,” and “overcome by desire or eagerness” are all recorded from around 1300. Mad in the sense “enraged, angry” arose after about 1400. This sense of mad is the usual colloquial term in the United States (the British are more likely to use angry ) and has been condemned by the arbiters of usage since the late-18th century. The sense “wildly lively, merry” is an Americanism, associated with jazz and African Americans, and dates to the early 1940s.
like mad (initially, for mad ) is quite old, from the 14th century. We take it today to mean “with great haste or energy,” but the original meaning was more literal: “in the manner of one who is mad.”
