The Chinese word "人种" is formed by combining the character "人" (rén), meaning "human" or "person", with the character "种" (zhǒng), meaning "seed", "kind", or "type". In this compound, "人" acts as a modifier to "种", specifying that the kind or type pertains to humans, thus yielding the meaning "human kind" or "human type", which directly translates to the concept of race or ethnicity.
