Właśnie napisał powieść.

English Translation

He wrote a story just now.

Is this not specifically “novel” rather than “story”? Wouldn’t “Story” be “opowieść”?

Powieść is definitely novel, not story. And story would be opowieść most often, but also press story = relacja prasowa. I wonder if you use story meaning fairy tale as well, like tell me a story, then it would be bajka?

I’ll report this next time I see it then.
