Origin: XX [etym. unknown]

Etymology: From Aeol. βρίζα appears PGr. *Ϝρίδ-ι̯α, which differs in vocalism from Lat. rādīx = rād-ī-c-s (with enlarging -c- as e.g. in genetrī-x); in both cases we have a ι̯α-, resp. ī-deriv. of a noun, which is also found in Germ. and Celt.: ONorse rōt f. `root' from PGm. *u̯rōt-, IE *u̯rād-, which may be seen also in Lat. rād-īx (cf. below); beside it, with i-stem and zero grade Goth. waurts, OE wyrt, OHG MHG wurz `herb, root', PGm. *u̯urt-i-, IE *u̯r̥d(-i)-; Celt., e.g. Welsh gwraidd coll. `roots' with ī-suffix but the root vocalism has not been explained. The Germ. and Celt. forms and ῥίζα cannot represent a weak- or reduced grade; in spite of Schwyzer 352 who wants to assume a vowel i representing a reduced grade. (Lat. rādīx, but not ONorse rōt, can represent IE *u̯rHd-, but in other forms there is no laryngeal.) So the foms cannot be explained as yet, and we must reckon with loans. (Vine UCLA Indo-European Studies I 1999, 5-30 does not solve the problem.) -- Toch. B witsako `root' remains to be explained (hypothesis by v. Windekens Lex. étym. s.v.). Further forms w. lit. in WP. 1, 288 Pok. 1167, W.-Hofmann s. rādīx. Cf. ῥάδαμνος, ῥάδιξ. Cf. also NGr. (Rhodos) ῥόζος `root', a cross of ῥίζα and ὄζος `branch' (Hatzidakis Άθ. 29, 180ff.).
