The Chinese word 争斗 (zhēngdòu), meaning "to fight" or "to contend", is a synonym compound formed by combining two characters with similar meanings. The first character, 争 (zhēng), means "to strive for" or "to dispute", while the second, 斗 (dòu), means "to fight" or "to struggle". When placed together, they reinforce and intensify the core concept of aggressive conflict or competition, creating a single, cohesive term that is more emphatic and nuanced than either character alone.
