Word Origin for trout
Old English trūht, from Late Latin tructa, from Greek troktēs sharp-toothed fish
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 root *tere- (see throw). In late 17c. slang, trusty trout was used in a sense of "confidential friend."
