英文词源
booty
booty: [15] Booty has no connection with boots. It came into English as butin (it did not finally lose its n until the 18th century), a borrowing from Old French butin, but Old French had got it from Middle Low German būte ‘exchange’ (whence German beute and Dutch buit ‘loot’), pointing to a prehistoric Germanic source *būtiōn. => filibuster, freebooter
booty (n.)
"plunder, gain, profit," mid-15c., from Old French butin "booty" (14c.), from a Germanic source akin to Middle Low German bute "exchange." Influenced in form and sense by boot (n.2) and in form by nouns ending in -y. Meaning "female body considered as a sex object" is 1920s, black slang.
