Origin & History of “root”
Root of a plant (OE) and root ‘dig with the nose’ (14th c.) 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.
