| 词汇 | vanish into thin air |
| 词源 | vanish into thin air. When Shakespeare used this phrase in The Tempest to describe ghosts “Melted into air, into thin air,” it was already in common use. All air was considered thin at the time, nothing being known about its varying density, and thin air was simply employed as an intensive. Other similar phrases of the day were vanished (or melted) into smoke, wind and even into liquid tears—all meaning the same, “to disappear.” |
