Četkam krzno.

Četkam is the 1st person singular present tense form of the verb četkati.

So četkam means I brush or I am brushing.

The ending -am here tells you the subject is I, which is why Serbian does not need the pronoun ja unless you want extra emphasis.

In Serbian, the subject is often left out because the verb form already shows who is doing the action.

So:

• Četkam krzno. = I brush / am brushing the fur.
• Ja četkam krzno. = I am brushing the fur.
  This version sounds more emphatic, as if you are stressing that I am the one doing it.

This is very common in Serbian.

The base verb is četkati.

It means to brush, usually with a brush. It can be used for hair, fur, clothes, teeth in some contexts, and other things depending on the object.

In this sentence:

• četkati = to brush
• četkam = I brush / I am brushing

Serbian present tense usually covers both the simple present and the present continuous meanings that English separates.

So Četkam krzno. can mean:

• I brush the fur
• I am brushing the fur

The exact meaning depends on context.

If you are describing what you are doing right now, it will usually be understood as I am brushing the fur.

Krzno means fur.

It usually refers to an animal’s fur, or sometimes fur as a material. In this sentence, it most naturally means the fur of an animal.

It is a neuter noun.

Its dictionary form is also krzno.

Krzno is the direct object of the verb četkam, so it is in the accusative case.

However, for many neuter singular nouns, the nominative and accusative forms are the same.

So:

• nominative: krzno
• accusative: krzno

That is why the word does not visibly change here.

Serbian has no articles like English a or the.

So krzno by itself can mean:

• fur
• the fur
• sometimes some fur

The exact meaning comes from context.

In a simple sentence like Četkam krzno., English will often translate it as I am brushing the fur or I brush the fur, but Serbian itself does not mark that distinction with an article.

A rough pronunciation guide:

• Č sounds like ch in chocolate
• e is like e in met
• t is a clear t
• k is a clear k
• a is like a in father
• m is m

So četkam is roughly CHET-kam.

For krzno:

• krz is a consonant-heavy cluster; the r is rolled or tapped
• o is a short pure o

Roughly: KRRR-zno or KRZ-no, depending on how comfortable you are with Serbian consonant clusters.

The stress is usually on the first syllable: ČET-kam KRZ-no.

Yes, you could also say Krzno četkam.

Serbian word order is more flexible than English because cases and verb endings carry a lot of grammatical information.

The most neutral order is usually:

• Četkam krzno.

If you say:

• Krzno četkam.

that can put more focus on krzno, as if contrasting it with something else.

For example:

• Krzno četkam, a rep ne.
  I’m brushing the fur, but not the tail.

So both are possible, but Četkam krzno is the plain, neutral version.

Četkati is imperfective.

That means it focuses on the action as ongoing, repeated, or habitual, rather than as a single completed event.

So Četkam krzno naturally suggests:

• I am brushing the fur
• I brush the fur regularly

If you want a perfective partner, Serbian often uses a related prefixed verb depending on context, such as iščetkati meaning something like to brush thoroughly / to finish brushing.

Yes. Serbian distinguishes between brushing and combing.

• četkati = to brush
• češljati = to comb

So if you are using a brush, četkati is the right choice. If you are using a comb, you would normally use češljati.

For fur, četkati krzno is very natural.

Here is the present tense of četkati:

• ja četkam = I brush
• ti četkaš = you brush
• on/ona/ono četka = he/she/it brushes
• mi četkamo = we brush
• vi četkate = you brush
• oni/one/ona četkaju = they brush

So your sentence uses the ja form:

• (Ja) četkam krzno.

Yes.

Like many Serbian present-tense sentences with an imperfective verb, Četkam krzno. can describe either:

1. an action happening now
   I am brushing the fur.

2. a habitual action
   I brush the fur.

Context tells you which one is meant.

For example:

• right now: someone asks Šta radiš? = What are you doing?
  You answer: Četkam krzno.

• habitual: someone asks what your job or routine involves
  You answer: Četkam krzno.

In this sentence, krzno behaves more like a mass noun, similar to English fur.

You are not talking about a fur as one individual item, but about the fur as a substance or covering.

If you wanted to talk about a fur coat or a fur garment, context would usually make that clear, but in a sentence like Četkam krzno, the most natural reading is actual animal fur.
