HOW TO USE -(으)ㄴ/는 김에

In this lesson we teach you the grammar pattern -(으)ㄴ/는 김에 that allows you to talk about doing one action while you’re already in the middle of or have already done another.

This is especially common when talking about errands, outings, or plans.

WHILE YOU’RE AT IT

The expression -(으)ㄴ/는 김에 is used to indicate that since one action is being done (or has just been done), another related action is done together—as if making use of the situation.

It adds nuance of taking the opportunity, killing two birds with one stone, or doing something while already out/engaged in another activity.
