이/가 marks the subject of the sentence, and 을/를 marks the object.

• 시험관이 = the examiner is the one doing the action
• 방향지시등을 = the turn signal is the thing being checked

So the structure is:

• 시험관이 → subject
• 방향지시등을 → object
• 확인했습니다 → checked / confirmed

This is a very standard Korean sentence pattern: subject + object + verb.

Here, 시험관 means examiner or test administrator.

In this sentence, it most naturally refers to the person giving or supervising a test, especially something like a driving test.

A useful thing to know is that 시험관 can also mean test tube in science contexts. Korean has many words whose meaning depends on context. In this sentence, because of 방향지시등 and 확인했습니다, it clearly means examiner, not test tube.

It is a compound noun made of several parts:

• 방향 = direction
• 지시 = indication
• 등 = lamp/light

So 방향지시등 literally means something like direction-indicating light.

In natural English, that is usually turn signal, indicator, or blinker, depending on dialect.

Korean is normally a subject-object-verb language, so the verb usually comes at the end of the sentence.

That is why the order is:

• 시험관이
• 방향지시등을
• 확인했습니다

In English, we say The examiner checked the turn signal.
In Korean, the natural order is more like The examiner the turn signal checked.

This is one of the biggest word-order differences English speakers notice when learning Korean.

확인했습니다 is the formal polite past tense form of 확인하다, which means to check, to confirm, or to verify.

Breakdown:

• 확인하다 = to check / confirm
• 확인했- = checked / confirmed
• -습니다 = formal polite ending

So 확인했습니다 means checked or confirmed in a respectful, formal style.

This kind of ending is common in:

• announcements
• reports
• written summaries
• formal explanations
• test or official situations

Both are polite, but they have different levels and styles.

• 확인했어요 = polite, everyday spoken style
• 확인했습니다 = more formal and official

Since this sentence sounds like something from a report, official explanation, or test situation, 확인했습니다 fits very well.

So the difference is not really the basic meaning, but the level of formality and tone.

Korean often does not mark singular and plural unless it needs to.

So 방향지시등을 확인했습니다 could mean:

• checked the turn signal
• checked the turn signals

The exact interpretation depends on context.

If the speaker wants to clearly mark plural, they might say 방향지시등들을, but in natural Korean that is often unnecessary and can sound a bit heavy unless the plural idea really matters.

Yes, very natural.

Because of the words 시험관 and 방향지시등, the sentence strongly suggests a testing situation such as a driving exam. It sounds like something from:

• a test report
• a narration of test procedures
• an explanation of what happened during the exam

If you wanted a slightly less formal spoken version, you could say:

• 시험관이 방향지시등을 확인했어요.

But the original sentence is very natural for formal narration.

A careful reading is close to:

• 시험관이 방향지시등을 확인했습니다
• si-heom-gwa-ni bang-hyang-ji-si-deung-eul hwak-in-haet-seum-ni-da

In natural speech, some parts may sound a bit smoother and faster than the spelling suggests.

A few helpful pronunciation notes:

• 시험관이 sounds like 시험과니 to many learners
• 방향지시등을 is a long compound noun, so it helps to break it into chunks:
  • 방향
  • 지시등
  • 을
• 확인했습니다 is often heard roughly like 화긴핻씀니다 in connected speech

You do not need to imitate every sound change perfectly at first, but it helps to know that real pronunciation is often slightly different from the spelling.

In very casual speech, Korean sometimes drops particles, especially when the meaning is obvious. However, in a sentence like this, especially in formal style, keeping the particles is much more natural and correct.

So:

• 시험관이 방향지시등을 확인했습니다. → correct and natural
• 시험관 방향지시등 확인했습니다. → sounds incomplete or unnatural in formal standard Korean

Because this sentence uses the formal ending -습니다, it is best to keep the grammar complete.

Not exactly.

• 보다 = to see / look at / watch
• 확인하다 = to check / confirm / verify

So 확인했습니다 suggests more than just looking. It implies checking to make sure something was correct, present, functioning, or properly done.

In a driving-test context, 확인했습니다 sounds better because the examiner is not just looking at the turn signal, but checking it.
