Etymology

edit

An isolated poetic adjective. If it originally meant "deceptive", from Proto-Indo-European *(s)teh₂y- (to steal), cognate with Sanskrit तायु (tāyu, thief), Avestan 𐬙𐬁𐬫𐬎 (tāyu, thief), Hittite [script needed] (tāyezzi), [script needed] (tāyazzi, to steal), Proto-Slavic *tajiti (to hide, conceal), etc. The suffix -σῐος may have been added directly to an unattested noun *τᾱΰς (*tāǘs) after the pattern of δημόσιος (dēmósios) from δῆμος (dêmos). Compare also τητάομαι (tētáomai, to lack, be in want, be robbed).
