State complement

Also known as: 状态补语 (kuàngtàibǔyǔ) and complement of state.

State complements describe an achieved state of an action. State complements are usually adjective phrases (adverb + adjective) but can take the form of verbal phrases, subject-predicate phrase or other complements. State complements that are adjective phrases often look the same as degree complements and thus often lumped together with degree complements in textbooks but some state complements are a very distinct form of complement. State complement phrases can be quite complex, at times having entire complement phrases act as the complement. It may be useful to think of more complex complement phrases as meaning "(verb) to the point of (complement)".
