"Więzienie jest w stolicy."

Translation: The prison is in the capital.

[Colin198350]

I checked, the speaker does not pronouce the final /e/ in więzienie - also I guess the singular verb should have given me a clue.

[Gerardd88]

The pronunciation here is correct. The "e" is pronounced.

[PonyDesu]

I do hear the "e" in "więzienie".

[PierreMDL]

Unless you meant any living speaker?

[Walkinthedog]

We have jails, the slammer, the hoosegow, the crowbar hotel and finally tank. Let's see some non native figure that one out. This is what makes it difficult if you aren't a native familiar with the lingo or language as civilized refer it as. Enjoy.

An alternative spelling for "jail" is "gaol".

[Jellei]

OK, added.

[Jas789]

Why "w" and not "na"?

[Jellei]

Both those words have their own collocations, "w" is (I think) a lot more common, 'the default', so to speak. I can't imagine anyone saying "na stolicy".
