Questions & Answers about taekbaehame neoheo dun sangjareul chajeuryeogo munjareul dasi hwaginhaesseo.

What does 택배함 mean here?

택배함 means a parcel box, delivery locker, or package locker.

It is made of:

• 택배 = parcel delivery / courier delivery
• 함 = box, container, compartment

So 택배함에 means in the parcel locker or into the delivery box.

Why is 에 used in 택배함에?

Here, 에 marks the location or destination of the action 넣다 (to put in).

So:

• 택배함에 넣다 = to put into the parcel locker

With verbs like 넣다, 에 often marks where something is put.

What does 넣어 둔 mean, and how is it different from just 넣은?

넣어 둔 comes from 넣어 두다.

-아/어 두다 means:

• do something and leave it that way
• do something in advance for later
• put something somewhere and keep it there

So:

• 넣은 상자 = the box that was put in
• 넣어 둔 상자 = the box that was put in and left there / put there beforehand

In this sentence, 넣어 둔 상자 suggests the box had already been placed in the locker earlier, and now the speaker is trying to retrieve it.

Why does 넣어 둔 come before ?
