natal (adj.)

late 14c., nowel, nouel "Christmas, the Feast of the Nativity," from Old French noel "the Christmas season," variant of nael, from Latin natalis (dies) "birth (day)," used in Church Latin in reference to the birthday of Christ, from natus, past participle of nasci "be born" (Old Latin gnasci), from PIE root *gene- "give birth, beget." The modern word in English, with the sense "a Christmas carol" (1811) probably is a separate borrowing from French. As a masc. proper name, it is from Old French, probably literally "of or born on Christmas."

"before birth," 1798; see ante- "before" + natal "pertaining to birth." Ante-nati was an old term for (in Scotland) those born before the accession of James I to the English throne, also used in U.S. in reference to those born in the colonies before the Declaration of Independence.
