More about irenic
Irenic 鈥減eaceful, conciliatory鈥� comes straight from Greek 别颈谤脓苍颈办贸蝉 鈥渂elonging to peace,鈥� a derivative of the noun 别颈谤岣梟脓. 贰颈谤岣梟脓 was also the name of the Greek goddess of Peace, the name of an 8th-century Byzantine empress, and the name of several Christian saints, whence the English female name Irene.
