Disability is a physical or mental condition that makes certain activities harder or limits how someone interacts with the world. It often has more to do with barriers in society than with a person’s abilities.
From 'disable' plus the noun suffix '-ity', based on Latin 'dis-' meaning 'not' and 'habilis' meaning 'able, handy'. Historically it focused on 'inability', but modern views stress difference and access rather than lack.
