英文詞源
- root
- root: Root of a plant [OE] and root ‘dig with the nose’ [14] are distinct words. The former was borrowed from Old Norse rót, which goes back ultimately to the Indo-European base *wrd-. This also produced Latin rādīx ‘root’, source of English radical, radish, etc. Root ‘dig’ is an alteration of an earlier wroot, which went back to Old English wrōtan. It is usually assumed that root ‘cheer, support’, which first emerged in America in the late 19th century, is the same word.
=> radical, radish - root (n.)
- "underground part of a plant," late Old English rot, from a Scandinavian source akin to Old Norse rot "root," figuratively "cause, origin," from Proto-Germanic *wrot (cognates: Old English wyrt "root, herb, plant," Old High German wurz, German Wurz "a plant," Gothic waurts "a root," with characteristic Scandinavian loss of -w- before -r-), from PIE *wrad- (see radish (n.), and compare wort). The usual Old English words for "root" were wyrttruma and wyrtwala.

- "dig with the snout," 1530s, from Middle English wroten "dig with the snout," from Old English wrotan "to root up," from Proto-Germanic *wrot- (cognates: Old Norse rota, Swedish rota "to dig out, root," Middle Low German wroten, Middle Dutch wroeten, Old High German ruozian "to plow up"), from PIE root *wrod- "to root, gnaw."
