How would you say "I like ____"

I'm wondering how you would say I like cats, or something. It doesn't matter what the noun is, just that there is "I like" in it.

It DOES matter what the noun is, as there are accusative cases and a kajillion other qualifiers, galore. But, "Lubię koty."; to your specific query.

Ja lubię...

Thanks.

Lubię....

The Polish language is so-called pro-drop language (from "pronoun-dropping"); i.e. personal pronouns are omitted in normal unmarked use - in this case I can infer the pronoun from the first person ending "-ę". If I'd say "Ja lubię" than what I really say is "I do (really) like it".

Or you can skip "Ja" and say "Lubię ......." (podmiot domyślny - implied subject), it sounds a bit more natural to skip the pronoun in such case.

So how would you say you like?

Ty lubisz - the full form. Lubisz - form with pronoun dropped. So:

Lubię pomidory = Ja lubię pomidory = I like tomatoes
Lubisz pomidory = Ty lubisz pomidory = You like tomatoes
Lubisz pomidory? = Czy lubisz pomidory? = Czy Ty lubisz pomidory? = Do you like tomatoes?

Hope this helps
