The Chinese word **租赁 (zūlìn)**, meaning "to lease" or "rental," is a **synonym compound** formed by combining two characters with similar meanings to create a broader, more formal term. The first character, **租 (zū)**, primarily means "to rent out" (from the owner's perspective) or "to pay rent," while the second character, **赁 (lìn)**, carries the meaning of "to hire" or "to borrow" (from the user's perspective). By joining them, the compound encompasses the entire two-way transaction of leasing—covering both the act of letting and hiring—resulting in a general, comprehensive term common in legal and business contexts.
