| 释义 | shaft (once / 327 pages) 1nv 2n 3nv The noun shaft refers to something that resembles a long, thin pole, such as the long part of an arrow between the tip and the feathers. The word shaft can describe all kinds of things that are long and thin, such a shaft of light or a spear or the handle of a golf club or the midsection of a long bone. A shaft can also be a long narrow tunnel, generally one that runs straight up and down, such as a mine shaft or an elevator shaft. You might think these items don’t have much in common, but think about their shape: they’re all long, straight, and thin.
