- turmoil (n.)
[turmoil 词源字典]
- 1520s, of uncertain origin, perhaps an alteration of Middle French tremouille "mill hopper," in reference to the hopper's constant motion to and fro, from Latin trimodia "vessel containing three modii," from modius, a Roman dry measure, related to modus "measure." Attested earlier in English as a verb (1510s), though this now is obsolete.[turmoil etymology, turmoil origin, 英语词源]
