noisy (adj.)

c. 1200, "sound of a musical instrument;" mid-13c., "loud speech, outcry, clamor, shouting;" c. 1300, "a sound of any kind from any source," especially a loud and disagreeable sound, from Old French noise "din, disturbance, uproar, brawl" (11c., in modern French only in phrase chercher noise "to pick a quarrel"), also "rumor, report, news," a word of uncertain origin, replacing Replaced native gedyn (see din).

According to some, it is from Latin nausea "disgust, annoyance, discomfort," literally "seasickness" (see nausea). According to others, it is from Latin noxia "hurting, injury, damage." OED considers that "the sense of the word is against both suggestions," but nausea could have developed a sense in Vulgar Latin of "unpleasant situation, noise, quarrel" (compare Old Provençal nauza "noise, quarrel"). Confusion with annoy, noisome, and other similar words seems to have occurred.

From c. 1300 as "a disturbance; report, rumor, scandal." In Middle English sometimes also "a pleasant sound." In 16c.-17c. "a band or company of musicians." Noises off, as a stage instruction in theater, "sound effects, usually loud and confused, made off stage but to be heard by the audience as part of the play," is by 1908.

adjective suffix, "full of or characterized by," from Old English -ig, from Proto-Germanic *-iga- (source also of Dutch, Danish, German -ig, Gothic -egs), from PIE -(i)ko-, adjectival suffix, cognate with elements in Greek -ikos, Latin -icus (see -ic). Originally added to nouns in Old English; used from 13c. with verbs, and by 15c. even with other adjectives (for example crispy). Adjectives such as hugy, vasty are artificial words that exist for the sake of poetical metrics.
