| 词源 | fifty-fifty. Fifty-fifty—50 percent for one party, 50 percent for the other—is still a common Americanism for “equally divid- ed.” An expression that one would guess is much older, it is first recorded in a 1913 Saturday Evening Post article, though it may date back to the late 19th century or earlier. |
