The word 格斗 is formed by combining two characters, each conveying a core aspect of combat. 格 carries the ancient meaning of "to strike" or "to fight hand-to-hand", focusing on the physical action and technique of close-quarters engagement. 斗 fundamentally means "to combat", "to struggle", or "to contest", emphasizing the broader concept of conflict and confrontation. When fused, these characters create a unified, vivid concept that perfectly encapsulates the essence of intense, skill-based physical fighting, such as in martial arts or hand-to-hand battle.
