From Proto-Balto-Slavic *dewin(t)as, reformed from earlier Proto-Balto-Slavic *newin(t)as (still preserved in Old Prussian, unless initial *n- is secondary and stems from Germanic influence) with *d- by analogy with Proto-Balto-Slavic *deśimtas (“tenth”), from Proto-Indo-European *h₁newn-o- with introduced suffix *-tos. (Per Trubačev, from Proto-Indo-European *newentos, *newn̥tos.) Baltic cognates include Lithuanian deviñtas, Latvian devîts, devîtais, Old Prussian newīnts. Also cognate with Latin nōnus (“ninth”) as well as Ancient Greek ἔνατος (énatos, “ninth”), Gothic 𐌽𐌹𐌿𐌽𐌳𐌰 (niunda, “ninth”), both with the same suffix *-tos.
