also antepartum, "occurring or existing before birth," 1908, from Latin phrase ante partum "before birth," from ante "before" (from PIE root *ant- "front, forehead," with derivatives meaning "in front of, before") + accusative of partus "a bearing, a bringing forth," from partus, past participle of parire "to bring forth" (from PIE root *pere- (1) "to produce, procure").
"one devoted to his nation," 1715, from national (adj.) in a now-otherwise-obsolete sense of "patriotic, characterized by attachment or devotion to one's own race or country or its institutions" (1711) + -ist. In 19c. Britain often particularly "one who advocates independence for a nation" (especially Ireland). Also used in theology for "one who holds to the divine election of entire nations," as distinguished from that of particular individuals (1836). Related: Nationalistic; nationalistically.
This etymology is doubted by some because no similar word exists in any other Romance language, but compare German Augensprossen "antlers," literally "eye-sprouts," for a similar formation. Later used of any branch of the horns. Related: Antlered (1813).
