From Middle English schaft, from Old English sċeaft, from Proto-West Germanic skaft, from Proto-Germanic skaftaz. Cognate with Dutch schacht, German German Schaft, Swedish skaft. In Early Modern English, shaft referred to the entire body of a long weapon, such that an arrow's “shaft” was composed of its tip, stale, and fletching. Over time, the word came to be used in place of the former stale and lost its original meaning.
Often paired with 'of' when describing light ('a shaft of light') or specific structures ('an elevator shaft').
