one-legged

The compound adjective 'one-legged' is a transparent construction from native English elements. Its first element, 'one', descends from the Proto-Germanic 'ainaz', which also gives us 'alone' and 'only', emphasizing singularity. The second element, 'leg', is a Middle English borrowing from Old Norse, replacing the Old English term 'sceanca'. The suffix '-ed', used to form participial and adjectival forms, is of ancient Germanic origin. The literal meaning, "having one leg," is a direct combination of these parts, with the figurative sense of imbalance or inequality arising logically from the physical notion of lacking equal support.

Structure: one (numeral) + leg (noun) + ed (adjective suffix) - one: From Old English 'ān', meaning the number one.
