언젠가 means someday or one day.

It usually suggests:

• the time is not specific
• the speaker thinks it will happen at some point in the future
• it can sound a little hopeful or reflective

So in this sentence, 언젠가 gives the feeling of I want to get a license someday, at some point in the future.

It is less specific than expressions like:

• 곧 = soon
• 내년에 = next year
• 나중에 = later

면허증 means license in the sense of the actual license document or card.

It is made up of:

• 면허 = license, certification, authorization
• 증 = certificate, document, card

So 면허증 is literally something like license certificate/card.

Depending on context, it could mean:

• a driver’s license
• another kind of official license

If you want to be more specific, you can say:

• 운전면허증 = driver’s license

을/를 is the object marker.

It marks the thing that is being received or wanted.

In this sentence:

• 면허증을 = the license as the object
• 받고 싶습니다 = want to receive/get

So 면허증을 is there because the speaker wants to get that thing.

A quick breakdown:

• 면허증 = license
• 을 = object marker
• 받고 싶습니다 = want to receive

Yes, 받다 basically means to receive.

In Korean, it is very natural to talk about officially getting a document or certificate with 받다. So 면허증을 받다 means to receive/get a license card.

This focuses on the idea of:

• being issued the license
• receiving it officially

In English, we often just say get a license, but Korean may express that as receiving the license.

받고 싶습니다 means want to receive/get.

It is built like this:

• 받다 = to receive
• remove 다 to get the stem: 받-
• add -고 싶습니다 = want to

So:

• 받다 → 받고 싶습니다

The grammar -고 싶다 is used to say want to do something.

Examples:

• 먹고 싶습니다 = I want to eat
• 가고 싶습니다 = I want to go
• 받고 싶습니다 = I want to receive

Because this sentence is formal, it uses 싶습니다 instead of 싶어요.

Because the grammar pattern is verb stem + 고 싶다.

So:

• 받다 → verb stem 받-
• 받고 싶습니다 = correct

You do not use the -아/어 form before 싶다.

Compare:

• 가다 → 가고 싶다
• 보다 → 보고 싶다
• 받다 → 받고 싶다

So 받고 싶습니다 is the normal and correct form.

Yes. 싶습니다 is a formal polite style.

So 언젠가 면허증을 받고 싶습니다 sounds appropriate in:

• interviews
• presentations
• written statements
• speaking politely to someone you do not know well

Less formal versions would be:

• 언젠가 면허증을 받고 싶어요. = polite, everyday style
• 언젠가 면허증 받고 싶어. = casual

It is understandable and grammatically correct, but the most natural wording depends on what exactly you mean.

There is an important nuance:

• 면허증을 받다 = receive the physical license/card
• 면허를 따다 = earn/get the license qualification, often by passing the test

So if you mean I want to get licensed someday, Korean speakers often say:

• 언젠가 면허를 따고 싶습니다.
• for a driver’s license: 언젠가 운전면허를 따고 싶습니다.

If you specifically mean the official document/card being issued, then 면허증을 받고 싶습니다 works well.

So this sentence is fine, but depending on context, 면허를 따고 싶습니다 may sound more natural.

These are related but not identical:

• 면허 = the license/qualification itself
• 면허증 = the license document/card
• 운전면허증 = driver’s license card
• 운전면허 = driving license qualification

Examples:

• 운전면허를 따다 = to get a driver’s license qualification
• 운전면허증을 받다 = to receive the driver’s license card

So in many situations:

• 면허를 따다 focuses on passing/earning it
• 면허증을 받다 focuses on receiving the actual card

Yes. Korean word order is flexible, especially with adverbs like 언젠가.

For example:

• 언젠가 면허증을 받고 싶습니다.
• 면허증을 언젠가 받고 싶습니다.

Both are possible, but 언젠가 면허증을 받고 싶습니다 is more natural and neutral.

Putting 언젠가 earlier in the sentence is common because it sets the time frame right away.

The subject is understood from context as I.

Korean often omits subjects when they are obvious. Since -고 싶습니다 expresses the speaker’s desire, it naturally implies I want to...

So even though 저는 is not written, the sentence is understood as:

• (저는) 언젠가 면허증을 받고 싶습니다.
• I want to get a license someday.

Adding 저는 is possible if you want emphasis or contrast:

• 저는 언젠가 면허증을 받고 싶습니다.

A natural everyday polite version is:

• 언젠가 면허증을 받고 싶어요.

A casual version is:

• 언젠가 면허증 받고 싶어.

If you mean earn/get a driver’s license, a very natural spoken version is:

• 언젠가 운전면허를 따고 싶어요.
• 언젠가 운전면허 따고 싶어.

So the choice depends on:

• your level of politeness
• whether you mean receive the license card or earn the license

A natural pronunciation is roughly:

• 언젠가 → eonjen-ga
• 면허증을 → myeonheo-jeung-eul
• 받고 싶습니다 → often sounds closer to bat-kko sip-seum-ni-da

A couple of helpful pronunciation notes:

• In 받고, the final ㄷ in 받 combines with the following ㄱ, so it sounds like 밧꼬 rather than a careful dictionary-style 받고
• In 싶습니다, the ㅂ니다 part is pronounced seum-ni-da

You do not need perfect romanization, but it helps to know the actual spoken sound may differ a little from the spelling.
