the.com/disability

means A physical, sensory, cognitive, or mental condition that affects how a person moves through, senses, or processes the world.

from From Latin 'dis-' (apart, not) plus 'habilis' (able, fit, handy — the same root that gives us 'able' and 'ability'). 'Habilis' itself traces to 'habere,' to hold or have, since being 'able' originally meant having the capacity to hold or handle something. So 'disability' literally means 'not-having-the-capacity' — a word built, tellingly, around the idea of lack rather than difference, which is exactly the framing disability advocates have spent decades pushing back against.
