Questions & Answers about kenkoushindan ga owatta monono, wakuchinsesshu wa mada owatte inai.

What does ものの mean here?

ものの means something like although, even though, or but.

So:

• 健康診断が終わったものの = Although the health checkup is over, ... = The health checkup has finished, but ...

It connects two facts that contrast with each other. In this sentence, the contrast is:

• one thing is finished
• the other thing is still not finished

Compared with けど or が, ものの sounds a bit more formal and often appears more in writing or careful speech.

Why is the verb 終わった placed before ものの?

Because ものの attaches to a plain clause.

Here, the clause is:

• 健康診断が終わった = the health checkup ended / has finished

Then ものの is added to that full clause:

• 健康診断が終わったものの = although the health checkup has finished

This is a common pattern:

• Verb (plain form) + ものの
• い-adjective + ものの
• na-adjective / noun + であるものの in more formal styles

So 終わったものの is grammatically normal.

How is ものの different from けど or ?
