Using "lai" as a dummy verb

The verb 来 (lái) can be used as a "dummy verb," similar to the way "do" is used in English. Imagine a bottle of pickles that you want to open but can't because the lid is so tight. You start passing it around to see who can open it, and no one is able to, until your beefy friend comes in and says, "我来!" He is saying, "Let me do it!"

Structure

The structure for using 来 as a dummy verb is very basic. Usually it is a very short phrase, kind of like "your turn!," "let me give it a shot!," or "you do it!" in English. Usually it is used with 你 or 我 as the subject, and it ends with the 来. Sometimes it can end with a 吧.

(让 +) Subj. + 来
