"Who do you love?" is one of the first questions that makes a language feel personal. In Serbian it becomes Koga voliš? - and the moment you answer with a real name or a family word, something clicks. The question is also a gentle introduction to the accusative case, because the person you love becomes the object of the sentence, and Serbian marks that shift with a change in the question word itself. It is a small thing, but it is one of those small things that opens a door.

This post walks you through the who/whom distinction in Serbian, gives you the basic answer patterns, and includes the original video so you can hear it spoken naturally. By the end, answering Koga voliš? should feel easy and a little bit warm.

Koga vs Ko - who and whom in Serbian

In Serbian, Ko means "who" as a subject - the person doing something. Koga means "whom" - the person receiving the action, the object of the verb. So you ask Ko voli? ("Who loves?") when you want to know the lover, and Koga voliš? ("Whom do you love?") when you want to know the beloved.

English blurs this distinction in everyday speech ("Who do you love?" instead of "Whom do you love?"), but Serbian keeps it clean and consistent. Once you hear the pattern a few times it feels completely natural, and it is a useful anchor for understanding the accusative case more broadly.

The pattern you will hear

Here are the core answers you will encounter and want to produce yourself. Notice how the family words shift into the accusative form:

The pattern is very regular for people: feminine nouns in -a take -u in the accusative, and masculine nouns add -a. Mum and dad both end in -a in their base form (mama, tata), so they follow the same feminine-style ending. Brat is a typical masculine noun, so it takes -a. A handful of examples really does cover most family vocabulary.

Hear it (carried forward)

The video below was part of the original post. Listen for the question and the answers - pay attention to how koga sounds in natural speech and how the answer follows immediately without any pause or filler. That smooth question-answer rhythm is worth practising out loud.

Try it

Write three answers to Koga voliš? using real family members or friends. Say each one aloud: Volim ___. Check that you are using the accusative form of the name or noun - that small ending change is the whole point of the exercise.

If you have a study partner or a language exchange friend, take turns asking and answering. It sounds simple, but the back-and-forth of a real question and a real answer cements the pattern far faster than reading it from a page.

Frequently asked questions

Is "koga" a formal word, or do everyday speakers use it?
Completely everyday. Koga voliš? is the natural, conversational way to ask the question - there is no more formal or more casual alternative. You will hear it in songs, in films, in family conversations. It is not textbook language at all.
What if I love a pet? Does the accusative still apply?
Yes, and in a lovely way - animate nouns (living beings, including pets) in Serbian use the genitive form for the accusative of masculine nouns. So a male dog named Maks would become Volim Maksa. For feminine-ending pet names it follows the regular -u pattern. Pets are definitely animate enough to count.
Do I always need to use the accusative when I answer "Koga voliš?"
Yes - the verb voliti (to love / to like) always takes a direct object, which means accusative. There is no way around it, but the good news is that the accusative for people follows very clear patterns. A few minutes of practice with family words and the ending clicks into place on its own.

I am Marina Petrovic, and Koga voliš? is honestly one of my favourite entry points to Serbian grammar - it is personal, it is real, and it quietly teaches the accusative without making a fuss about it. Once you are comfortable with this one, the other accusative patterns fall into place much more easily.
