Learn Hardcore Turkish: Ben ofiste kitap okuyorum. - I am reading a book at the office.

Ben means “I.” Turkish verbs are fully conjugated for person, so the subject is clear from the verb ending. Including Ben is optional and adds emphasis or clarity. Saying Ofiste kitap okuyorum is perfectly natural and still means “I am reading a book in the office.”

What does the -te in ofiste mean?

The -te suffix is the locative case marker, meaning “in” or “at.” It attaches to ofis (“office”) with vowel harmony (ofis + te = ofiste), so ofiste means “in the office.”

Why isn't there an article before kitap? Shouldn't it be “a book”?

Turkish has no separate word for “a” or “the.” An unmarked noun is usually indefinite (i.e., “a book”). If you want to stress “a,” you can add bir: bir kitap okuyorum (“I am reading a book”). Without bir, it’s still understood as “a book” in context.

Why doesn't kitap have a case ending? Don't direct objects need the accusative?

Direct objects take the accusative marker (-ı/-i/-u/-ü) only when they are definite or specific. Here kitap is indefinite (“a book”), so it stays unmarked. If it were “the book,” you’d say kitabı okuyorum.
