https://en.wikipedia.org/wiki/Moron_(psychology)
> Moron is a term once used in psychology and psychiatry to denote mild intellectual disability.[1] The term was closely tied with the American eugenics movement.[2] Once the term became popularized, it fell out of use by the psychological community, as it was used more commonly as an insult than as a psychological term. It is similar to imbecile and idiot.[3]
https://en.wikipedia.org/wiki/Imbecile
> The term imbecile was once used by psychiatrists to denote a category of people with moderate to severe intellectual disability, as well as a type of criminal.[1][2] The word arises from the Latin word imbecillus, meaning weak, or weak-minded.[3] It included people with an IQ of 26–50, between "idiot" (IQ of 0–25) and "moron" (IQ of 51–70).[4] In the obsolete medical classification (ICD-9, 1977), these people were said to have "moderate mental retardation" or "moderate mental subnormality" with IQ of 35–49.[5]
