When describing a specific type of impairment, be precise. For example, instead of saying someone's ability is "impaired", specify "visually impaired" or "cognitively impaired" for clarity.
Common error
Avoid using "impaired" as a catch-all term. If you know the specific nature of the impairment (e.g., motor skills, memory), use a more descriptive term to provide a clearer picture.
