Equative comparison with kao

The phrase after kao copies the case of the phrase before it.

A1 · Lesson 41 · Saying one thing is like another: kao

The full explanation, from the lesson that teaches this rule

When you want to say that someone or something is like someone or something else, Serbian uses one little word: kao. It means like, as, or the way that.

The good news first: kao never changes. It has no endings, no gender, no plural. You write it the same way in every sentence you will ever build.

The one thing you have to get right

kao stands between the two things you are comparing, and the phrase after it copies the case of the phrase before it. Think of kao as an equals sign: whatever case is on the left, put the same case on the right.

Watch the same noun, brat, on the two sides of two different sentences:

kao copies whatever case is already there
SentenceCase on both sidesWhy
Ana peva kao ptica.nominative + nominativeAna is the subject, so ptica stays in its dictionary form.
Volim ga kao brata.accusative + accusativega is the object, so brat becomes brata too.

Nobody says Volim ga kao brat. Once the left side is an object, the right side has to look like an object as well.

Two jobs kao does

The first job is a role or capacity — what someone works as, comes as, lives as. Here English usually says as.

  • On radi kao trener. — He works as a coach.
  • Ovde sam kao gost. — I am here as a guest.

The second job is a plain likeness — a comparison, often a little picture. Here English says like.

  • Pliva kao riba. — He swims like a fish.
  • Ova zima je hladna kao led. — This winter is cold as ice.

Adding an adjective

The noun after kao can carry an adjective, exactly as any noun can. The adjective agrees with that noun in gender, number and case — the agreement you already know — and the whole phrase still copies the case from the left side.

Left sidekao + phraseCase of the phrase after kao
Moj deda jekao stari lav.nominative, masculine
Volim ovaj gradkao drugu kuću.accusative, feminine
Gledam gakao dobrog prijatelja.accusative, animate masculine
Uzmi ovu knjigukao mali poklon.accusative, masculine — same shape as the nominative

kao is about being alike, not about being more. Brz je kao vuk says he is as fast as a wolf — the two are equal. Serbian has other ways to say that one thing beats another (brži od vuka), and those belong to a different lesson. If the meaning is equally, reach for kao.

A comma before kao appears in long sentences, but the short comparisons in this lesson are written without one: Jak je kao medved.
