tempest

英文词源

tempest

tempest: [13] Latin tempestās started off meaning nothing more alarming than ‘period of time’ (it was a derivative of tempus ‘time’, source of English temporary). Gradually, however, it progressed via ‘weather’ to ‘bad weather, storm’. Tempus moved in to take its place in the neutral sense ‘weather’, and provides the word for ‘weather’ in modern French (temps), Italian (tempo), Spanish (tiempo), and Romanian (timp). Other languages whose word for ‘weather’ comes from a term originally denoting ‘time’ include Russian (pogoda), Polish (czas), Czech (počasí), Latvian (laiks), and Breton (amzer).

tempest (n.)

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

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. Figurative sense of "violent commotion" in English is recorded from early 14c. Tempest in a teapot attested from 1818; the image in other forms is older, such as storm in a creambowl (1670s).
