- trout (n.)
[trout 词源字典]
- Old English truht "trout," in part from Old French truite, both from Late Latin tructa, perhaps from Greek troktes "a kind of sea fish," literally "nibbler," from trogein "to gnaw," from PIE *tro-, from root *tere- (1) (see throw (v.)). In late 17c. slang, trusty trout was used in a sense of "confidential friend."[trout etymology, trout origin, 英语词源]
