About This Root
From Old English duru (door), from Proto-Indo-European *dhwer- (doorway). One of the oldest words in English, cognate with Latin foris and Greek thyra. Beyond the literal door and doorway, compounds like outdoor/outdoors extend the concept to the space beyond the entrance. The word's simplicity belies its deep Indo-European ancestry.
