From LSJ
Russian (Dvoretsky)
κοινά: adv. сообща, вместе Soph.
Frisk Etymological English
Meaning: (for κοίνα or κοῖνα?) χόρτος H.
Origin: IE [Indo-European]X [probably] [610] *koino- grass
Etymology: Agrees completely with a Balto-Slavic word for hay, e. g. Lith. šiẽnas, OCS sěno χόρτος (Persson BB 19, 257). Lat. fēnum, faenum hay can hardly be combined with it, s. W.-Hofmann s. v. and Nachträge 1, 864f. However, Latte supposes that it is about common ground, so from κοινός.
