Borrowed from Ancient Greek τᾰρσός (tarsós, “the flat of the foot; the edge of the eyelid and its lashes”). Has been compared with Armenian թառ (tʻaṙ, “bar for drying grapes”), Old High German darra (“apparatus for drying fruits”), Swedish tarre (“frame for drying malts”), suggesting a derivation from Proto-Indo-European *ters- (“to dry”). However, for phonetic reasons this is uncertain.
