In this Adventure in Etymology, we’re opening doors to find the origins of the word door. A door [dɔː / dɔɹ] is: A portal of entry into a building, room, or vehicle, typically consisting of a rigid plane movable on a hinge. It may have a handle to help open and close, a latch to hold it closed, and a lock that ensures it cannot be opened without a key. It comes from Middle English dor(e) [ˈdɔːr(ə)] (door), from Old English duru [ˈdu.ru] (door, opening) from Proto-West-Germanic *dur (door, hatch, flap) from Proto-Germanic *durz (door, hatch, flap), from PIE *dʰwer- (door) [source]. Words from the same roots include forum, forensic and thyroid in English, dörr (door) in Swedish, drws (door, doorway) in Welsh, dvor (court, courtyard) in Slovak and ترس (tors – shield, buckler) in Persian [source]. Incidentally, in Old English one word for window was ēagduru [ˈæ͜ɑːɡˌdu.ru], or literally “eye-door”. Another was ēagþyrel [ˈæ͜ɑːɡˌθy.rel], or “eye-hole” [source].
