Complement

Complements are a a special type of structure found in modern Mandarin which follow verbs (or sometimes adjectives) and provide additional information. They can be as short as one character, or practically as long as a sentence. According to A Practical Chinese Grammar for Foreigners, complements "show the duration, quantity, degree, result, direction or possibility of an action; or to illustrate the state, number, degree of a thing"[1]. The Chinese word for complement is 补语 (bǔyǔ).

Complements are not a form of flattery (those are compliments)[2]; they're much more versatile than that! But because complements have no exact counterpart in English, they can be a little bit difficult to get the hang of at first. As is often the case, plentiful examples will help clarify!
