settoappu ga owatta.

セットアップ is a loanword from English setup. In Japanese, katakana is commonly used for foreign loanwords, especially in technology, business, and computing.

In this sentence, セットアップ usually means something like:

• software installation/setup
• device configuration
• system setup
• getting something ready for use

So it sounds very natural in a technical context.

が marks the thing that ended / finished.

The verb here is 終わる, which means to end or to be finished. Since 終わる is an intransitive verb, the thing that finishes is marked with が.

So:

• セットアップが終わった = The setup finished = The setup is done = Setup has ended

English often phrases this as I finished the setup, but Japanese may express it as the setup finished.

終わった is the plain past form of 終わる.

Conjugation:

• dictionary form: 終わる
• past plain form: 終わった

This happens because 終わる is a u-verb. Verbs ending in -わる like this change to -わった in the past plain form.

So:

• 終わる → 終わった

It does not become 終わりた.

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

So セットアップが終わった could mean:

• The setup is done
• The setup finished
• I finished setting it up
• We’re done with the setup

The exact English translation depends on the situation. Japanese often focuses more on the event or result than on explicitly naming the subject.

Yes. 終わった is plain/casual style.

A more polite version would be:

• セットアップが終わりました。

Both mean the same thing, but:

• 終わった = casual, everyday, plain
• 終わりました = polite

You would choose based on who you are talking to.

Good question. These two are related but used differently:

• 終わる = to end, to be finished (intransitive)
• 終える = to finish something (transitive)

So:

• セットアップが終わった = The setup finished / is done

But you could also say:

• セットアップを終えた = I finished the setup

The difference is that 終える sounds a bit more deliberate or controlled by someone, while 終わる simply states that the setup has come to an end.

In many situations, セットアップが終わった sounds very natural.

Yes, セットアップは終わった is possible, but the nuance changes.

• セットアップが終わった

  • neutral statement
  • focuses on the fact that the setup finished

• セットアップは終わった

  • adds contrast or topic marking
  • can sound like As for the setup, that’s finished
  • may imply something else is not finished

So が is often the most straightforward choice when simply reporting completion.

Not necessarily. Even though 終わる is intransitive, Japanese often uses intransitive verbs to describe a completed state without emphasizing who caused it.

So セットアップが終わった does not strongly mean the setup happened with no agent. It simply reports the result: the setup is finished.

In a computer context, this is very natural because the important point is the completion, not who performed each action.

Yes, it is natural, especially in everyday speech and in tech-related contexts.

Depending on the situation, other natural expressions include:

• セットアップが完了した

  • the setup has been completed
  • a bit more formal / technical

• セットアップは完了しました

  • polite and formal

• 設定が終わった

  • the configuration/setup finished
  • uses the native Japanese word 設定

But セットアップが終わった itself is perfectly normal.

Japanese normally does not use spaces between words in standard writing.

So this would usually be written as:

セットアップが終わった。

Spaces are sometimes added in learning materials to make the sentence structure easier to see. They are not part of normal Japanese spelling.

It is pronounced roughly like setto-appu.

A few points:

• セ = se
• ット has a small ッ, which creates a doubled consonant, so it sounds like sett-
• アップ = appu

So the rhythm is close to:

set-to-ap-pu

The final u sound in -pu is often light in normal speech.

Yes, depending on context, that can be a very good translation.

Because セットアップ can refer to software or system setup, possible natural English translations include:

• The setup is finished.
• Setup is complete.
• The installation is complete.
• The setup has been completed.

The best translation depends on what kind of setup is being talked about.
