Ability

There is no definitive solution to describing disability, as different people have different preferences, and those preferences can change over time. Above all, you should refer to people using the terms that they prefer.

More generally, the ASG supports the use of person-first language, because it is respectful and means that individuals are not defined by their disability. 

Person-first language
Put the person before their disability and don't use ‘the disabled’

Contemporary writing should put the person first before any detail about their experience or ability. This way, they are not defined by a disability. Also avoid language that constructs someone's experience negatively.

Common examples of person-first references include:

Phrases to usePhrases to avoid
person with disability

disabled person
person with special needs

people with lived experience
of disability

people of all abilities
person who is blindblind person

non-disabled person
At the same time, people will have individual preferences about how to refer to them. Use their preferred form where you know what that is.
Euphemisms
Avoid euphemisms such as ‘disAbility’ or ‘differently abled’
Often, well-intended terms can emerge to describe ability that also risk being patronising. Avoid terms such as ‘disAbility’, ‘differently abled’ and ‘diffAbled’. And take care not to imply that people are inspirational or courageous simply because they are living with disability.
