Sensitive Note

In reference to low intellectual ability, the terms retarded, retardation, and mental retardation are now usually perceived as insulting and have largely been replaced by other terms. There are several acceptable alternatives. In general, someone with a mental, physical, or emotional disability may be described as developmentally disabled, or as a person with a developmental disability. If it is specifically a mental disability, the person may be described as cognitively impaired or intellectually disabled. Such a person may be referred to as an individual with a cognitive impairment or a person with an intellectual disability. The slang term retard is a term of abuse used especially by children, though much less commonly than in the past. In both of its meanings, retard is perceived as insulting to disabled people. See also cripple.

Etymology

Origin of retarded

First recorded in 1800–10; retard + -ed 2

Explanation

Retarded is a word to describe someone who is mentally slow. This is a medical word that spread to slang, and is today considered very insulting and inappropriate. Some uses of retarded are harmless, like if you said wearing a backpack retarded or slowed down your progress on a hike. However, if you use retarded to mean stupid, you're on dangerous ground. Out of respect for people who have clinical mental retardation, this is considered an offensive term to throw around.
