What does disability mean?
Disability is a noun referring to a physical, sensory, intellectual, or mental condition that limits what a person can do — how they move, perceive, learn, or carry out daily activities. It also carries a legal sense: an officially recognized status that can qualify someone for benefits, accommodations, or protections under laws such as the Americans with Disabilities Act. In everyday use, the word appears constantly in phrases like "people with disabilities," "learning disability," and "disability benefits." While once used loosely to mean any disadvantage or incapacity, today its dominant meaning is tied to human health, access, and rights, and language around it continues to evolve — many advocates prefer person-first phrasing like "a person with a disability," though some communities embrace identity-first wording. Derived from the Latin root habilis ("able"), via Old French and Middle English, disability entered English in the early 17th century and remains one of the most socially significant words in modern vocabulary.
A physical, sensory, intellectual, or mental condition that limits a person's movements, senses, or activities.

The word "disability" didn't exist before the early 1600s — for centuries, English speakers had to describe limited ability without a single word for it.

Etymology of disability
Disability derives from the Latin root habilis, meaning "able" or "easy to handle," which also gives us able and ability. The word entered English in the early 17th century, formed by adding the prefix dis- (meaning "apart," "away," or "not") to ability, essentially reversing its sense. It shares this Latin ancestry with cognates such as enable, disable, and habilitate, all tracing back through Old French into Middle English usage. The term gradually shifted from describing any lack of capacity toward its modern, specific sense of a recognized condition limiting physical, sensory, or mental function.

How disability is actually used
Preferred modern usage favors person-first phrasing ("a person with a disability") or identity-first phrasing depending on community and individual preference; avoid outdated terms like "the disabled" as a blanket label when possible. In British English, "disability allowance" and "disability living allowance" are specific benefit names. The word is neutral in register and standard in both formal and informal contexts.
