Questions & Answers about Mam kartę biblioteczną.
Mam is the 1st person singular form of the verb mieć (to have).
So:
- mam = I have
- masz = you have
- ma = he/she/it has
Polish usually builds the subject information into the verb ending, so one word can already mean I have.
In Polish, the subject pronoun is often omitted because the verb already shows who is doing the action.
- Mam kartę biblioteczną. = I have a library card.
- Ja mam kartę biblioteczną. also works, but ja is usually added only for emphasis, contrast, or clarification.
For example:
- Ja mam kartę, ale on nie ma. = I have a card, but he doesn’t.
So leaving out ja is completely normal.
