historical usage of 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.”
