A little, from an English point of view.

• 백화점 = department store
• 매장 = store, sales floor, retail section

So 백화점 매장 means something like the store area in the department store or a shop/section at the department store.

In English, we would often just say at the department store, but Korean often includes 매장 to sound more specific about the shopping location.

-에서 marks the place where an action happens.

So in 백화점 매장에서, it means at/in the department store store area, and that is where the action 입어 봤어요 happened.

A useful contrast:

• 에 often marks destination or location of existence
• 에서 marks location of an action

Here, since trying on clothes is an action, 에서 is the natural choice.

This is a very common point of confusion.

In Korean:

• 이 = this
• 바지 = pants

But English treats pants as grammatically plural, while Korean treats 바지 as a single clothing item.

So:

• 이 바지 can mean this pair of pants
• In natural English, that often becomes these pants

So the Korean is not actually plural in the same way English is.

-를 is the object marker.

It shows that 이 바지 is the thing being acted on — in this case, the thing that was tried on.

So:

• 이 바지 = these pants / this pair of pants
• 이 바지를 = these pants, as the object of the verb

A quick pattern:

• after a vowel: -를
• after a consonant: -을

Since 바지 ends in a vowel sound, it takes -를.

It comes from:

• 입다 = to wear, to put on
• -아/어 보다 = to try doing something

So 입어 보다 literally means to try wearing.

When talking about clothes, the natural English meaning is:

• to try on
• to try it on

Then 봤어요 makes it past tense and polite, so:

• 입어 봤어요 = tried it on

Not really. Here, 보다 is being used as a helper verb in the grammar pattern -아/어 보다, which means to try doing something.

So in this sentence, 입어 보다 does not mean wear and see word-for-word in a normal English sense. It functions as one expression meaning try wearing or, more naturally, try on.

Yes, you will see both.

• 입어 봤어요
• 입어봤어요

The spaced version helps show the grammar more clearly:

• 입어
  • 보다

In everyday writing, the attached form is also very common. For learners, the spaced version is often easier because it makes the -아/어 보다 pattern more visible.

Korean often leaves out the subject when it is already understood from context.

So even though English needs I tried on these pants..., Korean can simply say:

• 백화점 매장에서 이 바지를 입어 봤어요

The speaker is understood from context. If you want to include it, you could say:

• 저는 백화점 매장에서 이 바지를 입어 봤어요

That would mean the same thing, but with more explicit emphasis on I.

Because Korean is typically a subject-object-verb language.

A very common Korean sentence pattern is:

• topic/subject
• place/time
• object
• verb

So this sentence is structured like:

• 백화점 매장에서 = where
• 이 바지를 = what
• 입어 봤어요 = did what

That is normal Korean word order.

-어요 is the standard polite speech level used in everyday conversation.

So 입어 봤어요 sounds:

• polite
• natural
• appropriate in most everyday situations

Related forms:

• 입어 봤어 = casual, informal
• 입어 봤습니다 = more formal

So this sentence is in a polite, everyday style.
