shaft
The physical meanings evoke a sense of linear rigidity and depth. Whether it is a hole in the ground or a metal rod, the imagery is always one of a strict, elongated axis. It suggests a conduit—something that allows movement or energy to pass from one point to another in a straight line.
Countable when referring to a specific physical object or beam (a drive shaft, a shaft of light). Uncountable when referring to the general concept of a vertical passage in mining terminology.
