Using “lái” as a Dummy Verb
来
How it works
In this grammar point, 来 (lái) does not mean physical movement. Instead, it works like a light or dummy verb, meaning something like:
let...
be the one to...
do it by...
It is often used when someone takes responsibility for an action.
The pattern
Subject + 来 (lái) + Verb Phrase
Example sentences
让我来介绍一下。
Let me introduce it.
这个问题我来回答。
I will answer this question.
谁来帮我一下？
Who will help me for a moment?
Key point
Here 来 (lái) is not about coming physically. It is about taking the action.
