"Wieża jest wysoka."

Translation: The tower is tall.

[kiddo-depido]

[MS_Genius88]

Tall should also be accepted, but it is marked wrong.

[SeanBC13]

I am clearing hearing "wierza"

[Okcydent]

In general (since few hundred years) rz is pronounced the same as ż.
I don't know if you wanted to say that you hear r and z pronounced as separate consonants but I don't hear it that way.

[JanNoww]

Dictionary says there is no such form for the verb "wierzyć", so it can be only understood ad "wieża", as I see.

[chce_polski]

Most towers by definition are tall, Duo

When is it not?
