"It was a strange friendship."

Translation: To była dziwna przyjaźń.

If you are using "to" why is the verb not in the neuter?

[immery]

I think, that when you can replace "it" with 'this/that" it translates to "TO", if you can replace it with a noun it= on/ona/ono depending on noun (and in declension).
if you cant replace "it" with either , then you skip it.

(it's just a theory I made up, so may not be 100% accurate)

[vytah]

The verb matches the noun, not "to".

Is there no Polish word derived from either kolega or Przyjciel for friendship as friendship is derived from friend
