The word 天诛 is formed by combining the character 天 (tiān), meaning "heaven" or "the heavens", with 诛 (zhū), meaning "to punish" or "to execute". Together, they create a compound term where 天 acts as the agent, modifying 诛 to convey the concept of "punishment from heaven" or "divine retribution", indicating a punishment inflicted by a celestial or supreme authority.
