Etymology Edit

Inherited from Old East Slavic девѧносъто (devęnosŭto), attested since 12th c., of unclear origin. With no parallels outside East Slavic—other Slavic branches point to *devętь desętъ (literally nine tens)—likely to be a late dialectal innovation (even more so considering that the higher decades are less frequent and more prone to innovations). Many explanations have been proposed and recently compared by Anikin, who cautiously supports *devę(t)no sъto 'nine-related hundred'.

Other hypotheses include Proto-Indo-European *h₁néwn̥(d)ḱomt (literally ninth ten), from *h₁néwn̥ (whence де́вять (dévjatʹ)) and *déḱm̥t (whence де́сять (désjatʹ)), with the ending influenced by съто (sŭto, hundred). Compare Latin nōnāgintā and Ancient Greek ἐνενήκοντα (enenḗkonta).
