What does idiotic mean?
Idiotic means extremely foolish, stupid, or absurd, usually describing an action, decision, plan, or way of thinking that displays a striking lack of judgment. The adjective is more emphatic and more informal than words such as unwise or mistaken, and it often conveys the speaker’s strong disapproval. “An idiotic mistake” is a common expression, while “absolutely idiotic” intensifies the judgment. The word ultimately comes through Latin from Greek, where its ancestor referred to someone private or uninitiated rather than a fool. Over time, its sense developed into a contemptuous term for someone regarded as ignorant or foolish, and the modern adjective preserves that strongly negative force. It is useful in conversation because it vividly signals not merely an error, but a decision so poorly judged that it appears absurd.

“Idiotic” comes from the Greek word for a private person, whose original sense was “uneducated” or “uninitiated,” before English narrowed it to a forceful word for foolishness.

Where does idiotic come from?
The adjective comes from Latin idiōticus, derived from Greek idiōtēs, “private person” or “layperson,” with the related adjective idiōtikos. The Greek term originally referred to someone not initiated into public affairs, but it came to mean an ignorant orsimple-minded person. English adopted the Latinized form in the 16th century and gradually developed its modern sense of “foolish or absurd.” Its relatives include idiom and idiomatic, which descend from the same Greek root idea of “one’s own” or “private”.
How idiotic is actually used
Strongly disparaging and informal in tone; it is more emphatic than merely “foolish” and should generally be used for behavior, decisions, or ideas rather than as a neutral description of a person.
