Result Complements: xong, thấy, ra, mất, kịp

A result complement sits right after the verb and tells you how the action ended:

• xong: finished (ăn xong = finish eating)
• thấy: perceived with the senses (nghe thấy, nhìn thấy, ngửi thấy)
• ra: figured out or realised (nghĩ ra, nhận ra, nhớ ra)
• mất: gone or lost, often with regret (quên mất = forgot, oops)
• hết: all of it, nothing left (bán hết = sold out)
• kịp: in time (đến kịp, chưa kịp)
• nổi: have the strength to, mostly in the negative (xách không nổi = too heavy to carry)

To say the result was not reached, put không before the verb or between the verb and the complement: không nhìn thấy, đi không nổi. được can often replace thấy, ra or nổi with the plain meaning can.
