From mid-15c. as "public unrest or disturbance." Verbs commote "to disturb, stir up" (1852), commove (late 14c.) are marked "rare" in Century Dictionary.

also hurlyburly, "commotion, tumult," 1530s, apparently an alteration of phrase hurling and burling, reduplication of 14c. hurling "commotion, tumult," verbal noun of hurl (v.). Shakespeare has hurly "tumult, uproar," and Hurling time (early 15c.) was the name applied by chroniclers to the period of tumult and commotion around Wat Tyler's rebellion. Scott (1814) has hurly-house "large house in a state of advanced disrepair." Comparison also has been made to dialectal Swedish hurra "whirl round" (compare hurry (v.)).

"violent storm," late 13c., from Old French tempeste "storm; commotion, battle; epidemic, plague" (11c.), from Vulgar Latin *tempesta, from Latin tempestas "a storm, commotion; weather, season; occasion, time," related to tempus "time, season" (see temporal).

Latin sense evolution is from "period of time" to "period of weather," to "bad weather" to "storm." Words for "weather" originally were words for "time" in languages from Russia to Brittany.

"noisy commotion," 1746, Cambridge student slang, of uncertain origin, perhaps related to rousel "drinking bout" (c. 1600), a shortened form of carousal. Klein suggests a back-formation from rouse (n.), mistaken as a plural (compare pea from pease).

early 15c., from Old French ferment (14c.), from Latin fermentum "leaven, yeast; drink made of fermented barley;" figuratively "anger, passion" (see ferment (v.)). Figurative sense of "anger, passion, commotion" in English is from 1670s.
