Etymology: With ῥάχις can be compared directly Lith. ražis `stubble' (beside which more usual rãžas `stubble, (fork)tooth, barren twig'), IE *u̯răǵh-i-; anl. u̯- is confirmed by ὀρήχου (ὀ- = Ϝ-) τῆς αἱμασιᾶς H. Beside it full-(lengthened)grade *u̯rāǵh- in ῥᾱχός, ῥηχός. Further analysis uncertain: it can be both verbal and nominal derivations, also enlargements of a root noun etc. Further connection with ῥαχία, ῥάσσω cannot be shown (rejected by Solmsen Wortforsch. 163n.1); orig. meaning `stitch, bump'?? -- WP. 1, 318 (after Lidén Ein balt.-slav. Anlautges. 15), Pok. 1180. -- Ϝραχ- cannot be derived from an IE form; is the word Pre-Greek?
