i bajireul ibeo bwado dwaeyo?

Korean and English divide clothing words differently.

• 이 means this
• 바지 means pants/trousers

In Korean, 바지 is usually treated as a single noun, even though in English pants is grammatically plural. So 이 바지 is literally something like this pair of pants, but natural English translation is these pants.

That is why 이 바지를 입어 봐도 돼요? is naturally translated as May I try on these pants?

를 is the object particle.

It marks 바지 as the thing being acted on. In this sentence, the action is 입다 meaning to wear/put on, so 바지 is the object of that action.

• 바지 = pants
• 바지를 = the pants, as the thing being worn/tried on

In casual speech, Korean speakers sometimes drop object particles, but here 를 is completely normal and standard.

입다 means to wear or to put on clothes such as:

• shirts
• jackets
• dresses
• pants

So for pants, 입다 is the correct verb.

Korean uses different verbs depending on what you wear:

• 입다 = wear clothes
• 신다 = wear shoes
• 쓰다 = wear a hat / glasses in some contexts? Actually for hats it is 쓰다
• 끼다 = wear rings / gloves
• 메다 = wear or carry something over the shoulder, like a backpack

So because 바지 is clothing you put on your body, 입다 is the right choice.

Here, 보다 does not mean to see in the literal visual sense.

In grammar, -아/어 보다 attached to a verb means to try doing something.

So:

• 입다 = to wear / put on
• 입어 보다 = to try wearing / try on

This is a very common Korean pattern:

• 먹어 보다 = try eating
• 가 보다 = try going
• 해 보다 = try doing

So 입어 봐도 comes from 입어 보다, and the overall idea is try it on.

This is because 입다 is being connected to another verb, 보다.

To do that, Korean changes 입다 into the -아/어 connecting form:

• dictionary form: 입다
• stem: 입-
• connected form: 입어

Then:

• 입어 보다 = to try wearing

So 입어 is just the form needed before 보다.

-아/어 봐도 되다 means it is okay if I try doing... or more naturally, may I try... ?

Breaking it down:

• 입어 보다 = try wearing
• 입어 봐도 = even if I try wearing / if I try wearing
• 돼요 = it is okay / it is allowed

So:

• 이 바지를 입어 봐도 돼요? = Is it okay if I try on these pants? = May I try on these pants?

This is a very common way to ask permission in Korean.

돼요 comes from 되다, which often means to become, but in this pattern it means to be okay, to be allowed, or to be possible.

So in permission expressions:

• 해도 돼요 = it is okay to do it / you may do it
• 가도 돼요? = may I go?
• 앉아도 돼요? = may I sit down?
• 입어 봐도 돼요? = may I try it on?

So 돼요 is what makes the sentence sound like asking permission.

Yes, there is a small but important difference.

• 입어도 돼요? = May I wear it?
• 입어 봐도 돼요? = May I try it on?

The 보다 part adds the idea of trying the action. In a clothing store, if you want to ask whether you can go into the fitting room and see if it fits, 입어 봐도 돼요? is the better choice.

Without 보다, the sentence can sound more like asking permission to actually wear it, not specifically to test it.

Yes. -요 makes it polite in the standard everyday style.

이 바지를 입어 봐도 돼요? is natural and polite enough for situations like:

• speaking to a store clerk
• speaking to someone you do not know well
• everyday polite conversation

If you want to sound a little softer or more formal, you could also say:

• 이 바지를 입어 봐도 될까요?

That sounds slightly more careful and customer-service-like, similar to May I try on these pants?

Great question. Both are commonly seen, but the standard spacing is usually:

• 입어 봐도

This is because 보다 is originally a separate verb used as an auxiliary verb after the main verb.

However, in real life, many people write it 붙여서 as:

• 입어봐도

You will see both in messages and casual writing. For learners, it is safest to remember the standard form as 입어 봐도.

In some situations, yes, but the most natural meaning here is Can I try on these pants?

Because of -어 보다, the sentence strongly suggests trying the action rather than simply doing it for regular use.

So in a store, the listener will almost certainly understand:

• May I try on these pants?

If you removed 보다, then Can I wear these pants? would become more likely.

Yes. 이 means this/these near the speaker. You can change it depending on distance.

• 이 바지 = these pants / this pair of pants here
• 그 바지 = those pants near you, or the pants we already mentioned
• 저 바지 = those pants over there

So in a store, if the pants are right in front of you, 이 바지 is the normal choice.

Here are a few levels:

• 이 바지를 입어 봐도 돼요?
  Standard polite

• 이 바지 입어 봐도 돼요?
  Also very natural; the 를 is dropped in speech

• 이 바지 입어 봐도 될까요?
  A bit softer and more polite

• 이 바지 입어 봐도 돼?
  Casual, for friends or someone younger

So the original sentence is already very natural and useful.
