More about irenic
Irenic “peaceful, conciliatory” comes straight from Greek eirēnikós “belonging to peace,” a derivative of the noun eirḗnē. Eirḗnē 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. The bewildering number of dialect forms (irā́nā, irḗnā, ireinā, etc.) point to a non-Greek origin. Irenic entered English in the second half of the 19th century.
