散漫 (sǎn màn) is an adjective describing a lack of discipline, order, or focus—often in behavior, habits, or work style. The first character 散 means 'scattered' or 'dispersed', suggesting things are not gathered or organized; the second character 漫 means 'unrestrained' or 'casual', implying absence of boundaries or control. Together, they paint a vivid picture of looseness and inconsistency—not merely relaxed, but neglectful of structure or responsibility.

This word is commonly used to criticize poor time management, inconsistent effort, or careless attitudes—especially in academic, professional, or self-discipline contexts. It carries a mild-to-moderate negative connotation, stronger than 'casual' but less harsh than 'reckless'. While it can describe people ('a散漫 student'), it’s more frequently applied to habits, schedules, or organizational styles ('a散漫 approach to study'). It’s rarely used for objects or animals unless metaphorically personifying them.
