Here, 맡겼어 comes from 맡기다, which means to entrust, to leave something in someone’s care, or to check something in.

In this sentence, it means something like:

• I left the bag at the storage office
• I checked the bag in at the luggage storage
• I entrusted the bag to the storage desk

So this is not just putting a bag somewhere. It suggests giving it to a person or service to keep safe.

을 is the object particle. It marks 가방 as the thing being acted on.

So:

• 가방을 = the bag as the object
• 맡겼어 = left/entrusted

In other words, the bag is the thing that was left in storage.

Because 가방 ends in a consonant, it takes 을. If the noun ended in a vowel, it would take 를 instead.

In this sentence, 에 marks the place or destination where the bag was entrusted.

So:

• 보관소에 맡기다 = to leave something at the storage office

Here, 보관소 is functioning almost like the recipient or destination of the action.

This is why 에 is natural. It is not just saying where the action happened physically, but where the bag was placed into care.

That is a very common question.

• 에서 usually marks the place where an action is actively carried out
• 에 often marks a destination, target, or place something goes to

With 맡기다, Korean normally uses 에 for the person or place you entrust something to:

• 친구에게 맡겼어 = I left it with a friend
• 보관소에 맡겼어 = I left it at the storage office

Using 보관소에서 맡겼어 would sound unnatural for this meaning.

맡겼어 is:

• past tense
• informal/casual speech

So it is something you would say to:

• a friend
• someone younger
• someone you are close to

The more polite version would be:

• 가방을 보관소에 맡겼어요.

And the dictionary form is:

• 가방을 보관소에 맡기다

It is formed like this:

• dictionary form: 맡기다
• stem: 맡기-
• past marker: -었-
• casual ending: -어

So:

• 맡기 + 었어
• becomes 맡겼어

This happens because Korean often contracts forms when conjugating, so 기 + 었어 becomes 겼어.

Korean very often omits the subject when it is clear from context.

So 가방을 보관소에 맡겼어 could mean:

• I left the bag at the storage office
• He left the bag at the storage office
• She left the bag at the storage office

Usually, the listener already knows who is being talked about.

In everyday Korean, leaving out the subject is completely normal and very common.

보관소 means a storage place, luggage storage area, or left-luggage office.

Depending on context, it could refer to:

• a train station storage office
• an airport luggage storage service
• a department store or museum bag check
• another staffed place where items are kept for you

It does not automatically mean a coin locker. For a locker, Korean often uses words like 물품보관함 or 락커 depending on the context.

So 보관소 often suggests a storage desk, counter, or service.

This is an important nuance.

• 두다 / 놓다 = to put or leave something somewhere
• 맡기다 = to leave something in someone’s care, to entrust it

So:

• 가방을 의자에 뒀어 = I left the bag on the chair
• 가방을 보관소에 맡겼어 = I left the bag with the storage service

With 맡기다, there is usually an idea of:

• safekeeping
• responsibility
• another person or service looking after it

Yes. Very often.

Examples:

• 친구한테 가방을 맡겼어. = I left my bag with a friend.
• 직원에게 짐을 맡겼어요. = I left my luggage with an employee.

So 맡기다 works with both:

• a person
• a place/service

In your sentence, 보관소 is the place or service receiving the bag.

In natural speech, it sounds roughly like:

• 가방을 → 가방을
• 보관소에 → 보관소에
• 맡겼어 → roughly 맏꼈어

That last part changes in pronunciation because Korean sound rules affect how consonants are heard in connected speech.

So even though it is written 맡겼어, the spoken form sounds closer to 맏꼈어.

Yes. Korean word order is flexible as long as the particles make the roles clear.

These are all possible:

• 가방을 보관소에 맡겼어.
• 보관소에 가방을 맡겼어.

Both mean essentially the same thing.

The difference is usually just emphasis:

• 가방을 first: focus a bit more on the bag
• 보관소에 first: focus a bit more on where it was left

The verb usually stays at the end.
