The word "idiot" traces back to Greek idiōtēs, meaning a private citizen or layperson (as opposed to a public figure or expert). Over time, it evolved in Latin (idiota) to imply ignorance due to lack of education. By the 14th century, English adopted it to describe intellectual deficiency, reflecting societal shifts linking isolation from knowledge with foolishness.
