Definition of the word idiocy

The word "idiocy" has its roots in the 14th century Latin word "idiota," meaning "private person" or "layman." During this time, the term referred to an ordinary person as opposed to a professional or expert. Over time, the meaning of the word shifted to refer to someone who is ignorant, foolish, or lacking in intelligence. By the 16th century, "idiocy" was being used in English to describe mental retardation or intellectual disability. The term was often used in a derogatory manner to describe people with disabilities or those who were considered to be inferior. Today, the term "idiocy" is often used in a more neutral sense to describe foolish or absurd behavior, rather than as a pejorative term for individuals with intellectual or developmental disabilities.
