今天和同事讨论了一个问题，需要客户确认，然后他说了一句 

“Let them make a call”

我很疑惑，好像我们没有在讨论要和客户通电话来确定，当我准备问他时，想来还是谷歌一下。

果不其然，Make a call有两个意思：

1，打电话 To call someone, as on a phone or via the Internet.

I have to make a call, so I’m going to step outside for a minute.

How do you make a call on Skype? Can you show me?

2，做决定 To make a decision (about something).

I know that neither option is ideal, but you have to make a call soon.

It’s too much pressure being a doctor. If you don’t make the right call about a patient’s course of treatment, they could end up dead!

由此可见，同事的意思应该是让客户来做决定吧。所以具体是哪个意思还得根据上下文来确定。
