English speakers borrowed noel from the French word noël, which is also used for both the Christmas holiday and a Christmas carol. It can be traced further back to the Latin word natalis, which can mean “birthday” as a noun or “of or relating to birth” as an adjective. (The English adjective natal has the same meaning and is also an offspring of natalis.) Noels were being sung in Latin and French for centuries before English-speakers started using the word to refer to Christmas carols in the 18th century. An early use of noel (spelled Nowel) to mean “Christmas” can be found in the text of the late 14th-century Arthurian legend Sir Gawain and the Green Knight.

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 acquired its current figurative meanings concerned with returning to the past. The variants hearken and harken (also very old words meaning "to listen") are also used, with and without back, as synonyms of hark back.
