Identity-first language is often used by communities, for example the Deaf and autistic communities, who believe that identity-defining features cannot be separated from the individual. This is pertinent in languages such as English where adjectives typically precede nouns, e.g. "talented child" instead of "a child with talent."

Some believe differentiating the language we use for disability from language we use for other adjectives may perpetuate stigma rather than mitigate it.

Identity-first language is also prompted by individuals who believe that their disabled embodiment is essential to and should not be separated from them or their humanity. This usage also can signal how some disabled individuals view disability as an integral part of their cultural identity.

Some scholars have noted how person-first language is used to refer to children with disabilities but not often used for nondisabled children, this creates a separation with person-first language being used to discuss disability but identity-first language is used to discuss other identity neutral or positive attributes.

Some view the use of identity-first language as a way to highlight disability as an identity category since identity-first language is used for other categories including race, gender, and sexual orientation.
