un-，直到，来自PIE*ant, 前面，词源同ante-, anterior, til-, 直到，词源同till,因此，该词实际上两个部分表达的是同一个意思。比较unto.

until

until: see till

until (prep.)

c. 1200, from till (prep.). The first element is un- "as far as, up to" (also in unto), from Old Norse *und "as far as, up to," from Proto-Germanic *und- (cognates: Old English oð "up to, as far as," Old Frisian, Old Saxon, Gothic und), from PIE *nti-, from root *ant- "front, forehead" (see ante). The two syllables have the same meaning. Originally also used of persons and places. As a conjunction from c. 1300. Similar formation in Swedish intill, Danish indtil. The Modern German equivalent, bis (Old High German biaz), is a similar compound, of Old High German bi "by, at, to" and zu "to."
