doorless

the word 'doorless' is a transparent english compound formed by combining the native english noun 'door' with the productive adjective-forming suffix '-less'. the old english noun 'doru' or 'dur' (door) descends from proto-germanic 'durz', which in turn derives from the proto-indo-European root 'dhwer-', meaning 'doorway, gateway, courtyard'. the suffix '-less' originates from the old english adjective '-lēas', meaning 'free from, devoid of', itself from a germanic root meaning 'loose'. the logic of the word is perfectly literal: the suffix '-less' negates or removes the quality of the noun it attaches to, thus 'doorless' directly and logically describes something that is without a door.

Structure: door (a hinged, sliding, or revolving barrier) + less (without) door (from old english 'duru'/'dor', meaning door, gate, portal; of germanic origin) + less (from old english '-lēas', meaning devoid of, free from; a suffix forming adjectives)
