Questions & Answers about Lubię smażone pieczarki.
Lubię means I like. It comes from the infinitive lubić.
The ending -ę shows 1st person singular in the present tense, so the verb itself already tells you the subject is I.
Polish often leaves out subject pronouns when they are obvious from the verb ending.
So:
- Lubię smażone pieczarki. = I like fried mushrooms.
- Ja lubię smażone pieczarki. also works, but ja adds emphasis, as if you were saying I like fried mushrooms.
Pieczarki is the plural of pieczarka.
It usually means button mushrooms or champignons, not mushrooms in the broadest possible sense. The more general word for mushrooms is grzyby.
So this sentence is specifically about pieczarki, not necessarily all kinds of mushrooms.
