Conjugation and context of 一本気

Hello, wasn’t sure where to put this. I just learned a new batch of vocabulary and was confused by the context and examples. 一本気 (one track mind) is given as a noun and na adjective. So fat, so good.

For the context, it gives three example where 一本気 is followed by の. For example, 一本気の人.
But in all the example sentences, it is followed by な.

Are these bad, or misleading, examples? Or am I missing some grammar point on the use of na and no?

Hello! =)

You can find a pretty detailed explanation here:


Is 一本気 a の-adjective?

I saw examples with の outside as well, but adjective type isn’t noted.

Thank you for the link to that article. It was enlightening, even though it’ll take a while to click.

You’re welcome! And don’t worry, you’ll find plenty of these little bumps on your learning road, hehe. The fun thing is, in the future you’re going to encounter this and other grammar points you struggled with at first and realize that they’re sounding natural to you and that your studies are paying off. Such a nice feeling, haha!
