Origin: IE [Indo-European] [775] *h₃eḱt- `eight'.

Etymology: From *ὄγδοϜος (oldcor. [ὀγ]δόϜα), perhaps to ὀκτώ after the example of ἑπτά: ἕβδομος (s. v.). Sommer Zum Zahlwort 24f. considers also the possibility of a regressive voice-assimilation in *oḱtu̯-os as in ἕβδομος from * septm-os, both with anaptyctic - ο-. A zero-grade -u-, -u̯- beside the long diphthongue in ὀκτώ (IE *oktōu̯) has also been supposed in Oldphryg. οτυϜοι Ϝετει `in the eighth year' and Goth. ahtuda ' ὄγδοος'. Diphthonges are also found in OHG ahtow-i pl. `eighth' as office and in the lengthened grade Lat. octāvus (with unclear ā). Details in Schwyzer 595 w. n. 3, Sommer l.c., W.-Hofmann s. octō. Cf. Rix, Hist. Gr. 172: *(h₃)eḱth₃u-h₂o-.
