Hark Back Got Its Start in Hunting

Hark, a very old word meaning "to listen," was used as a cry in hunting. The master of the hunt might cry "Hark! Forward!" or "Hark! Back!" The cries became set phrases, both as nouns and verbs. Thus, a "hark back" was a retracing of a route by dogs and hunters, and to "hark back" was to turn back along the path. From its use in hunting, the verb soon acquired its current figurative meanings. The variants hearken and harken (also very old words meaning “to listen”) are also used, with and without back, as synonyms of hark back.
