«As the improved cherry came from the Pontos area (cf. Κερασοῦς "rich in cherries", town on the Pontos), the name is probably Anatolian as well. Given its intervocalic σ, the form must be Anatolian or Pre-Greek. For the suffix, cf. ▶-θíασος, ▶-κάρπασος, which too are of foreign origin. Assyr. karšu has also been adduced. Cf. on ▶κράνον 'cornelian cherry'. Gr. κέρασος, -íα, κεράσιον were borrowed into many languages: Asiatic names of the cherry-tree and the cherry, like Arm. ker̄as, Kurd. ghilas, and in the West, Lat. cerasus, -ium, VLat. ★cerasia, ★ceresia, -ea; from Latin came the Romance and Germanic forms like MoFr. cerise, OHG chirsa > Kirsche.
