When talking about identifies, people-first language can be used as it avoids defining a person in terms of their disability, such as “people with disabilities” rather than “the disabled,” “special needs” or other terms; or “people experiencing homelessness” instead of “the homeless.” However, some advocates prefer identity-first language (“a disabled person”). Asking people about their preference in terminology is a best practice.
