n.Middle English merger of Old English dor (neuter; plural doru) “large door, gate,” and Old English duru (fem., plural dura) “door, gate, wicket;” both from Proto-Germanic *dur- (cf. Old Saxon duru, Old Norse dyrr, Danish dør, Old Frisian dure, Old High German turi, German Tür). The Germanic words are from PIE *dhwer- “a doorway, a door, a gate” (cf. Greek thura, Latin foris, Gaulish doro “mouth,” Gothic dauro “gate,” Sanskrit dvárah “door, gate,” Old Persian duvara- “door,” Old Prussian dwaris “gate,” Russian dver’ “a door”). The base form is frequently in dual or plural, leading to speculation that houses of the original Indo-Europeans had doors with two swinging halves. Middle English had both dure and dor; form dore predominated by 16c., but was supplanted by door. A door is what a dog is perpetually on the wrong side of. [Ogden Nash] Allow for further action or discussion. For example, This will’s terms leave the door open for fighting among the heirs. This metaphoric expression transfers the invitation implied by an open door to future events. Also see open the door to. see at death’s door; at one’s door; back door; beat a path to someone’s door; behind closed doors; close the door on; darken one’s door; foot in the door; keep the wolf from the door; lay at someone’s door; leave the door open; lock the barn door; next door to; open doors; open the door to; see someone out (to the door); show someone out (to the door); show someone the door.
