Questions & Answers about Ona voli seriju, ali ja više volim vesti.

Why are ona and ja included if the verb already shows who the subject is?

In Serbian, subject pronouns are often omitted because the verb form already tells you the person:

• voli = he/she/it likes
• volim = I like

So you could say:

• Voli seriju, ali više volim vesti.

But in your sentence, ona and ja are included for contrast:

• Ona voli seriju, ali ja više volim vesti.

This gives the sense of she likes X, but I like Y more. English often needs the pronouns; Serbian often uses them only when they are emphasized or contrasted.

Why is it seriju and not serija?

Because seriju is in the accusative case, which is used for the direct object of the verb voleti (to like/love).

The base form is:

• serija = series

But after voli / volim, the thing being liked is the object, so it changes:

• serija → seriju

This is a regular pattern for many feminine nouns ending in -a:

• knjiga → knjigu
• škola → školu
• serija → seriju
