sukoa wo kakuninsuru.

を marks スコア as the direct object of the verb.

So in スコアを確認する, the thing being checked is the score.

A very literal breakdown is:

• スコア = score
• を = object marker
• 確認する = to check / to confirm

So the structure is basically check the score.

確認する means to check, to confirm, or to verify.

It often sounds a little more formal or deliberate than a very simple look at. It suggests making sure something is correct or checking the status of something.

For example, 確認する is commonly used for:

• checking information
• confirming details
• verifying results
• making sure something is correct

So スコアを確認する is not just see the score, but more like check/confirm the score.

確認 is a verbal noun, often called a suru-noun. That means it can act like a noun by itself, but it becomes a verb when you add する.

• 確認 = confirmation / checking
• 確認する = to confirm / to check

This is very common in Japanese, especially with words of Chinese origin.

Other examples:

• 勉強する = to study
• 相談する = to consult
• 練習する = to practice

So 確認する is a standard and very common verb form.

Japanese normally puts the verb at the end of the sentence.

So the basic order here is:

• スコア = score
• を = object marker
• 確認する = check

This is a typical Japanese pattern:

object + を + verb

English usually says check the score, but Japanese says something more like the score + check.

する is the plain/dictionary form.

You often see the dictionary form in:

• vocabulary lists
• headings
• instructions
• app menus
• neutral descriptions of actions

If you wanted a polite sentence, you would say:

• スコアを確認します。

Both are correct, but する is the basic form you usually learn first and the one dictionaries use.

It is a Japanese word in the sense that it is commonly used in Japanese, but it originally comes from English score.

It is written in katakana, which is often used for:

• loanwords
• foreign names
• some sound effects
• emphasis

So:

• スコア = score

This is very normal Japanese usage, especially in games, sports, tests, and apps.

In modern Japanese, the particle を is usually pronounced o, even though the kana is written を.

So:

• スコアを確認する
• pronounced roughly: sukoa o kakunin suru

The kana を is mainly used as the object particle. In modern speech, it does not usually sound different from お.

Normally, standard Japanese is written without spaces:

• スコアを確認する。

The spaced version is often used in teaching materials to make the structure easier to see.

So for learners, you may see:

• スコア　を　確認する。

But in real Japanese text, the natural form is:

• スコアを確認する。

Yes. Both can work, depending on context.

• check the score is often the most natural translation
• confirm the score can also be correct, especially if the context is more formal or about verification

In many everyday contexts, 確認する is broader than a single English verb, so the best translation depends on what is happening.

For example:

• in a game app: check the score
• in a report or official setting: confirm the score

Yes, but the nuance is different.

• スコアを見る = look at the score
• スコアを確認する = check/confirm the score

見る focuses more on the act of seeing. 確認する focuses more on checking or making sure.

So if someone just wants to view the score, 見る may be enough. If the idea is to verify or review it, 確認する is more natural.

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

So スコアを確認する。 does not explicitly say:

• I check the score
• You check the score
• Please check the score
• To check the score

The exact meaning depends on context.

In something like a menu, button, or instruction, it might simply mean:

• Check score
• Check the score

Japanese often sounds natural without stating the subject if the situation already makes it clear.

The word 確認 is made of two kanji:

• 確 = certain / definite
• 認 = recognize / acknowledge

Together, 確認 gives the sense of making sure or confirming something.

You do not always need to break words down by kanji to understand them, but in this case the kanji do match the overall meaning quite well.
