Questions & Answers about Czytam książkę o wojnie.
Because after the verb czytać (to read), the direct object normally goes in the accusative case.
- dictionary form: książka = book
- accusative singular: książkę
So:
- Czytam książkę. = I am reading a book / I read a book
This is very common in Polish: the thing directly affected by the action often changes form.
Czytam is the 1st person singular form of czytać, so it means:
- I read
- I am reading
In Polish, the present tense of an imperfective verb can often translate into English as either a simple present or a present continuous, depending on context.
Examples:
- Czytam codziennie. = I read every day.
- Teraz czytam książkę. = I am reading a book now.
Because in Polish, the verb ending already shows the subject.
- czytam = I read / I am reading
So ja (I) is usually unnecessary unless you want emphasis or contrast.
Compare:
- Czytam książkę. = I’m reading a book.
- Ja czytam książkę. = I’m the one reading the book / I am reading the book (with extra emphasis)
