shaftとは 意味・読み方・使い方

語源

From 中期英語 schaft, from 古期英語 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.
