Korean often leaves out the subject when it is obvious from context. So 주방 선반에 머리를 부딪혔어요 naturally means I hit my head on the kitchen shelf if the speaker is talking about themselves.

If needed, you could add 제가 or 나는, but in everyday Korean it is usually unnecessary.

With body parts, Korean often omits words like my, your, or his/her when the owner is clear from context.

So 머리를 부딪혔어요 is understood as hit my head, not just hit a head.

This is very natural in Korean:

• 머리가 아파요 = My head hurts
• 손을 씻었어요 = I washed my hands

Here is the breakdown:

• 주방 = kitchen
• 선반 = shelf
• 주방 선반 = kitchen shelf
• 에 = on / against / at (depending on context)
• 머리 = head
• 를 = object particle
• 부딪혔어요 = bumped / hit (polite past tense)

So the sentence is literally something like:

[On/against] the kitchen shelf, [my] head, hit/bumped.

A more natural English translation is I hit my head on the kitchen shelf.

In this sentence, 에 marks the place or thing that the head came into contact with.

With verbs like 부딪히다, Korean often uses this pattern:

A에 B를 부딪히다
= to hit/bump B against A

So:

• 선반에 = against/on the shelf
• 머리를 = the head
• 부딪혔어요 = hit/bumped

In English we often say hit my head on the shelf, but Korean uses 에 to mark that target of contact.

Because 머리 is the thing that got hit, so it is treated as the direct object of the verb.

• 머리를 = the head as the object
• 선반에 = the shelf as the place/target of impact

So Korean is structured more like:

I hit [my head] against [the shelf].

That is why 머리 takes 를.

It comes from 부딪히다.

• dictionary form: 부딪히다
• polite past: 부딪혔어요

This verb means to bump into, to strike against, or to hit against.

In this sentence, it describes accidental contact, like bumping your head on something.

Yes, in most everyday situations it sounds accidental or unintentional.

So 머리를 부딪혔어요 usually means:

• I bumped my head
• I hit my head by accident

If you want a more deliberate sense of hitting, Korean may use other verbs depending on the situation.

They come from different dictionary forms:

• 부딪히다 → 부딪혔어요
• 부딪치다 → 부딪쳤어요

In everyday speech, these are often very close in meaning, and both can be translated as bumped into / hit against. Many learners will see both.

For this sentence, though, the form actually used is 부딪혔어요, so the dictionary form is 부딪히다.

Korean usually puts the verb at the end, so the sentence naturally builds up to the action.

This order is:

주방 선반에 + 머리를 + 부딪혔어요
against the kitchen shelf + my head + hit

That may feel backwards compared with English, but it is normal in Korean.

Because Korean uses particles like 에 and 를, the word order can sometimes move around for emphasis. For example, 머리를 주방 선반에 부딪혔어요 is also understandable. But the original sentence sounds natural and standard.

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

So 부딪혔어요 is polite and natural in many situations:

• talking to someone you do not know well
• talking to a coworker
• talking to a teacher
• everyday polite conversation

Other possible styles are:

• 부딪혔다 = plain form
• 부딪혔습니다 = more formal

Yes. In English, those are very close, and Korean often does not force the same distinction English does.

This sentence most naturally communicates the event: I hit/bumped my head on the kitchen shelf.

If you wanted to focus more on the head itself as the subject, Korean could also use a structure like 머리가 ... 부딪혔어요, but 머리를 부딪혔어요 is a very common way to say I hit my head.
