词源

词源 1
PIE word
*wréh₂ds
From Middle English rote, root, roote (“the underground part of a plant”), from late Old English rōt, from Old Norse rót (“root”), from Proto-Germanic *wrōts (“root”), from Proto-Indo-European *wréh₂ds (“root”); Doublet of wort, radish, and radix.
Cognate with Scots ruit, rute (“root”), Danish rod (“root”), Faroese and Icelandic rót (“root”), Norwegian and Swedish rot (“root”).
词源 2
From Middle English wrōten (“to dig with the snout”), from Old English wrōtan, from Proto-West Germanic *wrōtan, from Proto-Germanic *wrōtaną (“to dig out, to root”). Related to Old English wrōt (“snout; trunk”). Loss of initial w- probably due to influence from the related noun (Etymology 1).
词源 3
