saisyuu kekka wo kakuninsita.

It is pronounced:

さいしゅう けっか を かくにんした。

Word by word:

• 最終 = さいしゅう
• 結果 = けっか
• を = usually pronounced o
• 確認した = かくにんした

A more natural written form would usually be 最終結果を確認した。 without spaces.

They are almost certainly there just to help a learner see the parts of the sentence.

In normal Japanese writing, you would usually write this as:

最終結果を確認した。

Japanese normally does not use spaces between words the way English does.

最終結果 means final result, final results, or the final outcome, depending on context.

Breakdown:

• 最終 = final, last
• 結果 = result, outcome

Together, they form a noun phrase meaning final result.

Because 最終 can directly modify a noun.

So:

• 最終結果 = final result
• 最終電車 = last train
• 最終回 = final episode

Japanese often makes compact noun combinations like this, especially in formal or written language.

You can sometimes see 最終の結果, but it is less natural here. 最終結果 is the standard, more natural expression.

を marks the direct object of the verb.

In this sentence, the thing being checked/confirmed is:

最終結果

So:

• 最終結果を = the final result(s) as the object
• 確認した = checked / confirmed

In other words, を shows what was confirmed.

確認した is the plain past form of 確認する.

Breakdown:

• 確認 = confirmation, checking, verification
• する = to do
• 確認する = to confirm / to check / to verify
• 確認した = confirmed / checked / verified

This is a very common pattern in Japanese:

• 勉強する = to study
• 勉強した = studied
• 電話する = to call
• 電話した = called

These are often called suru-verbs.

Because 確認する has a more specific meaning than 見る.

• 見る = to look at, to see
• 確認する = to check, confirm, verify, make sure

So 最終結果を確認した does not just mean someone looked at the final result. It suggests they checked it carefully or confirmed it.

This makes the sentence sound more precise and a bit more formal.

Yes, the subject is omitted.

Japanese often leaves out the subject when it is obvious from context.

So this sentence could mean:

• I confirmed the final result.
• We confirmed the final result.
• He/She/They confirmed the final result.

The sentence itself does not tell you who did it. You understand that from the surrounding context.

It is in the plain past style, not the polite style.

• 確認した = plain past
• 確認しました = polite past

So:

• 最終結果を確認した。 = plain style
• 最終結果を確認しました。 = polite style

The plain form is not automatically rude. It is very common in:

• casual conversation
• diary-style writing
• reports
• notes
• narration

If you are speaking politely to someone, you would usually say 確認しました instead.

Yes. Japanese nouns usually do not show singular/plural the way English nouns do.

So 結果 can mean:

• result
• results

Depending on context, 最終結果を確認した could mean:

• confirmed the final result
• confirmed the final results

English forces you to choose singular or plural more clearly than Japanese does.

No, not in this sentence.

確認する is normally a transitive verb here, so the thing being confirmed takes を, not が.

So this is correct:

• 最終結果を確認した。 = Someone confirmed the final result.

If you use が, you would need a different structure, such as passive:

• 最終結果が確認された。 = The final result was confirmed.

So:

• を = marks the thing that someone confirmed
• が = would usually mark the subject of a different sentence pattern

Yes, it is a complete sentence.

Japanese sentences do not need an explicit subject if the meaning is clear from context. Since the verb 確認した is fully conjugated, the sentence is grammatically complete.

It is a very natural kind of short sentence in Japanese, especially in writing such as:

• work notes
• status updates
• reports
• narratives

So even though it may feel short to an English speaker, it is completely normal Japanese.
