덕분에 means thanks to or due to, and it usually implies a positive result.

So in this sentence, 사이드미러 덕분에 means thanks to the side mirrors.

Compare:

• 덕분에 = because of X, and the result is good/helpful
• 때문에 = because of X, more neutral, but often used when the result is negative or just factual

Examples:

• 친구 덕분에 시험에 합격했어요.
  = I passed the exam thanks to my friend.

• 비 때문에 경기가 취소됐어요.
  = The game was canceled because of rain.

You could say 사이드미러 때문에 평행 주차가 쉬웠습니다, but 덕분에 sounds more natural because the side mirrors helped.

Yes, it is a Korean word in the sense that Koreans use it normally, but it is a loanword from English: side mirror.

Korean often borrows English words and writes them in Hangul. These borrowed words may not always match standard English usage exactly, but they are common in Korean.

So:

• 사이드미러 = side mirror

A native Korean equivalent exists in some contexts, but 사이드미러 is very common in everyday speech.

Because 쉬웠습니다 comes from 쉽다 (to be easy), and in Korean, the thing that is easy usually takes the subject marker 이/가, not the object marker 을/를.

So:

• 평행 주차가 쉬웠습니다
  = Parallel parking was easy.

This is different from English, where we might think of parking as the thing someone did. In Korean, the sentence is structured more like:

• Parallel parking = subject
• was easy = description of that subject

A similar example:

• 한국어가 어려워요.
  = Korean is difficult.

Not:

• 한국어를 어려워요
  That would be wrong in this pattern.

평행 주차 means parallel parking.

Breakdown:

• 평행 = parallel
• 주차 = parking

Together, they form the noun phrase parallel parking.

In Korean, many noun phrases are built this way, with one noun modifying another.

Yes, that is a very helpful literal way to understand it.

• 평행 주차가 = as for / the thing called parallel parking, it is...
• 쉬웠습니다 = was easy

So the literal structure is:

• Thanks to the side mirrors, parallel parking was easy.

That literal understanding helps explain why 가 is used.

쉬웠습니다 comes from the adjective 쉽다, which means to be easy.

Breakdown:

• 쉽- = stem
• -었- = past tense
• -습니다 = formal polite ending

Because of sound changes, 쉽 + 었습니다 becomes 쉬웠습니다.

So:

• 쉽다 = to be easy
• 쉬워요 = it is easy
• 쉬웠어요 = it was easy
• 쉬웠습니다 = it was easy (formal)

Because 쉬웠습니다 means was easy, not is easy.

This suggests the speaker is talking about a specific situation or experience in the past, such as one parking attempt or a particular occasion.

Compare:

• 평행 주차가 쉬워요.
  = Parallel parking is easy. / Parallel parking is easy for me.

• 평행 주차가 쉬웠습니다.
  = Parallel parking was easy. / It was easy to parallel park.

So the past tense here probably refers to a completed event.

쉬웠습니다 is in the formal polite style.

This style is common in:

• speeches
• presentations
• news
• formal writing
• polite customer-facing situations

A less formal but still polite version would be:

• 사이드미러 덕분에 평행 주차가 쉬웠어요.

That means the same thing, but sounds more conversational.

Because Korean often omits pronouns and other information when they are understood from context.

In English, we often say:

• I was able to parallel park easily thanks to the side mirrors.

In Korean, if the speaker is obviously talking about their own experience, I does not need to be stated.

So the sentence naturally focuses on:

• the helpful cause: 사이드미러 덕분에
• the result: 평행 주차가 쉬웠습니다

This omission is very normal in Korean.

Yes, but the nuance changes.

• 평행 주차가 쉬웠습니다
  This simply states that parallel parking was easy.

• 평행 주차는 쉬웠습니다
  This sounds more like as for parallel parking, it was easy and may imply contrast, such as:

  • parallel parking was easy, but something else was difficult

So 가 is the more neutral and natural choice here if you are just describing the situation.

It is pronounced approximately like deok-bbu-ne.

A useful pronunciation note:

• 덕분에 is often pronounced with a tense ㅃ sound in actual speech:
  • [덕뿌네] approximately

That happens because of Korean sound rules. You do not need to change the spelling, but it helps to know why the pronunciation may sound stronger than the written ㅂ suggests.

Yes, a little.

The Korean order is:

• 사이드미러 덕분에 = thanks to the side mirrors
• 평행 주차가 = parallel parking
• 쉬웠습니다 = was easy

So the sentence is basically:

• Thanks to the side mirrors, parallel parking was easy.

This is actually a very normal Korean structure:

1. reason/cause
2. subject
3. predicate at the end

Korean verbs and adjectives usually come at the end of the sentence.

No, that would be incorrect.

With 쉽다 (to be easy), the thing that is easy takes 이/가, not 을/를.

So the correct form is:

• 평행 주차가 쉬웠습니다

Not:

• 평행 주차를 쉬웠습니다

If you want a structure with 를, you would need a different verb. For example:

• 평행 주차를 했습니다.
  = I did parallel parking. / I parked in parallel.

But with easy, use 가.

By itself, it most naturally refers to a particular past situation because of 쉬웠습니다.

So it sounds like:

• Thanks to the side mirrors, parallel parking was easy (that time / in that situation).

If you wanted to say it is generally easy, you would more likely say:

• 사이드미러 덕분에 평행 주차가 쉬워요.
  = Thanks to the side mirrors, parallel parking is easy.

So the tense helps tell you whether the speaker means a specific experience or a general statement.
