| 词汇 | even keel |
| 词源 | even keel. The expression to get things on an even keel, “to make things move smoothly,” dates back to at least the early 19th century. It, of course, derives from the nautical term an even keel, which one early writer defined this way: “A ship is said to swim on an even keel when she draws the same quantity of water abaft as forward.” |
