Which word describes a person who seeks to avoid societal connections?

The term that best describes a person who seeks to avoid societal connections is "recluse." A recluse typically chooses to live away from others and deliberately limits social interaction, often preferring solitude to companionship. This behavior can stem from a variety of reasons, including personal preference, social anxiety, or a desire to focus on individual pursuits without the distractions of societal obligations or relationships.

The other terms do not convey the same meaning: "companion" refers to someone who shares in social interactions and relationships with others, which is the opposite of avoiding societal connections. "Fellow" denotes a companion or member of a group with shared interests, while "accomplice" implies partnership in wrongdoing, thus involving social connection rather than avoidance. Hence, "recluse" is the most accurately fitting choice for describing someone who actively seeks to avoid societal ties.
