The Chinese word 追赶 (zhuīgǎn) is a compound verb formed by combining two synonymous characters, 追 (zhuī), meaning "to chase" or "to pursue", and 赶 (gǎn), meaning "to rush after" or "to catch up with". This combination follows a common lexical pattern in Chinese where two verbs with related meanings are paired to create a single, more expressive word that intensifies the core action; in this case, the compound emphasizes not just the act of pursuing, but doing so with a sense of urgency and determination to overtake or reach the target, thus conveying the nuanced meaning of "to chase after", "to run after", or "to strive to catch up".
