Etymology
Origin of autism
First recorded in 1910–15, for an earlier sense; coined in 1944 by Austrian-American psychiatrist Leo Kanner (1894–1981), for the current sense (in the phrase infantile autism ); from German Autismus (in the earlier sense), from New Latin; aut- + -ism
Explanation
Autism is a neurological condition that's marked by differences in learning styles, passionate interests in specific subjects, repetitive motion, and sometimes difficulty with language and communication. The word autism is taken directly from the Greek root auto, meaning “self.” Because autistic people may display a wide variety of characteristics, autism is defined as a range of conditions, known as the autism spectrum. This spectrum varies from those who have a hard time with social interaction to people who aren't able to speak. In some cases, autism is a diagnosis given by a doctor, while in others it's embraced by a person who self-identifies as autistic. A person who has autism is described as autistic.
