Questions & Answers about Mam dwie książki w torbie.
Yes. Mam means I have.
In Polish, the verb ending often tells you who the subject is, so you usually do not need to say ja for I.
- mam = I have
- masz = you have
- ma = he/she/it has
So Mam dwie książki w torbie is perfectly natural without ja.
If you said Ja mam dwie książki w torbie, that would add emphasis, like I have two books in the bag.
Polish does not have articles like English a/an and the.
So:
- książki can mean books
- w torbie can mean in a bag or in the bag
The exact meaning depends on context. This is very normal in Polish.
