One thing to remember Liz Polish grammar is hard for a non speaker the suffix at the end of words changes depending when you're referring to a male or female, past/present/future, a person or a thing. If you practice you'll get the hang of it.
I can already tell, even in the early stages of learning Polish, that this will be a struggle!!
Moim ulubionym kolorem jest różowy.
Could someone explain why it has to be in this particular tense? It is because "kolor" is masculine?
