The Chinese word 付费 (fù fèi) is a modern verb-object compound formed by combining the verb 付 (fù), meaning "to pay", with the noun 费 (fèi), meaning "fee" or "cost". This logical and transparent construction follows a common Mandarin syntactic pattern where an action is directly paired with its object, resulting in a term that literally means "to pay a fee" and is used broadly to mean "to pay (for a service)", "to pay charges", or as an adjective meaning "paid" (as in paid content).
