A "slip" refers to a minor mistake or error, often occurring in writing or speech. It can happen when someone accidentally writes the wrong word, misspells a name, or mispronounces a term. These slips are usually unintentional and can be corrected easily. In psychology, a "slip of the tongue" is a specific type of slip where a person says something different from what they intended. This phenomenon is often linked to the subconscious mind and can reveal underlying thoughts or feelings. Such slips can happen to anyone, including well-known figures like politicians or celebrities.
