Inherited from Proto-Balto-Slavic *-āˀtas, from Proto-Indo-European *-eh₂tos. Technically, could also reflect Proto-Indo-European *-eh₃tós, though, this suffix is encountered only sporadically in lemmas of uncertain origin, e.g. Ancient Greek κῑβωτός (kībōtós, “coffer, wooden box, container”). See also athematic Ancient Greek -ής (-ḗs) (gen. -ῆτος (-êtos)), attested for instance in ἀργής (argḗs, “shiny”), πένης (pénēs, “poor”), βλής (blḗs, “thrown”).
In loanwords, reflects Latin -ātus, Ancient Greek -ᾰτος (-ătos) or Proto-Indo-Iranian *-ātas as in demotic Church Slavonic креватъ (krevatŭ, “bed, coach”), borrowed from Ancient Greek κράββατος (krábbatos, “bed”), or Proto-Slavic *xorvatъ from a Scythian ethnonym, rendered as Χοροάθος (Khoroáthos) in Ancient Greek.
