A more thorough explanation:

Definition: Idiocy is an old-fashioned term used to describe a condition where a person is born without any ability to reason or use their intellectual faculties. It is also known as idiopathic insanity.

Example: In the past, people with Down syndrome were often labeled as "idiots" or "imbeciles" due to their intellectual disabilities. However, we now know that this is a harmful and inaccurate way to describe them.

Explanation: The example illustrates how the term "idiocy" was once used to describe individuals with intellectual disabilities. However, this is no longer an acceptable or accurate way to refer to them. It is important to use respectful and inclusive language when talking about people with disabilities.
