The Chinese word **催化剂 (cuīhuàjì)** for "catalyst" is a transparent compound formed through morphological derivation. It combines the verb **催化 (cuīhuà)**, meaning "to catalyze" (itself a compound of **催**, "to urge," and **化**, "to change/transform"), with the suffix **剂 (jì)**, which denotes an agent or chemical substance. Thus, the term literally and logically means "an agent that urges/accelerates transformation," directly reflecting the function of a catalyst in chemistry. This construction follows a common Chinese word-formation pattern where an action/process (催化) is paired with a nominalizing suffix (剂) to create a noun for the enabling substance.
