idiot

An idiot is someone who doesn't seem to know what they're doing or saying.

When we call someone an idiot, it usually means that their actions or words are silly or show a lack of common sense. For example, you might say that someone who does something reckless without thinking about the consequences is being an idiot. It's not always meant as a serious insult - sometimes people use it to describe themselves when they make a silly mistake. However, if used in a harsh tone, it can be quite hurtful. The word "idiot" can also be used in phrases like "idiotic behavior," which refers to actions that are foolish or ridiculous.
