Pacijent vidi krv.

Pacijent is nominative singular because it is the subject of the sentence.

Krv is accusative singular because it is the direct object, the thing being seen.

So the structure is:

• pacijent = subject
• vidi = verb
• krv = direct object

Serbian does not have articles like English the and a/an.

So Pacijent vidi krv can mean:

• The patient sees blood
• A patient sees blood
• sometimes even Patient sees blood, depending on context

Serbian usually leaves definiteness to context instead of marking it with a separate word.

Because the accusative singular of krv happens to be the same as its nominative singular form.

That can feel strange to an English speaker, because you expect the object form to look different. But in Serbian, some nouns have the same form in more than one case.

So here:

• nominative: krv
• accusative: krv

Even though the form is the same, its role in the sentence is different.

Not all feminine nouns in Serbian end in -a.

Krv belongs to a group of feminine nouns that end in a consonant. This group includes words like:

• krv = blood
• noć = night
• stvar = thing

So the noun’s gender is something you often just have to learn along with the word.

Vidi is the 3rd person singular present tense form of videti, meaning to see.

In this sentence it agrees with pacijent, which is singular.

A few present-tense forms of videti are:

• vidim = I see
• vidiš = you see
• vidi = he/she/it sees
• vidimo = we see
• vidite = you all / formal you see
• vide = they see

It can cover both, depending on context.

Serbian present tense often corresponds to both English:

• sees
• is seeing

So Pacijent vidi krv could describe:

• a general situation
• something happening right now

Context tells you which reading is intended.

This is a very common question.

• videti = to see
• gledati = to look at / to watch

So:

• Pacijent vidi krv = the patient sees blood
• Pacijent gleda krv would sound more like the patient is looking at the blood

In many situations, English speakers overuse gledati because English look and see can overlap a bit. Serbian keeps them more clearly separated.

Yes. Serbian word order is more flexible than English because case helps show who is doing what.

The most neutral order here is:

• Pacijent vidi krv.

But other orders are possible for emphasis or style, such as:

• Krv vidi pacijent.
• Pacijent krv vidi.

These alternatives are not the default neutral wording, but they are grammatically possible in the right context.

No, not usually.

Serbian often leaves subject pronouns out when they are not needed. The verb form already shows the person, and context usually shows who is meant.

So instead of saying:

• On vidi krv

you would often just say:

• Vidi krv

However, in the sentence you were given, the subject is already stated as pacijent, so adding on would usually be unnecessary.

This word is tricky for English speakers because it has no written vowel.

Krv is pronounced as one syllable, with the r acting like the center of the syllable. In Serbian, r can do that.

So do not force a full extra vowel like ku-rv or ke-rv if you can avoid it.

A rough guide:

• start with k
• make a short Serbian r sound
• end with v

It is best to think of it as a compact one-syllable word: krv.

Yes. Serbian uses both Latin and Cyrillic scripts.

So:

• Latin: Pacijent vidi krv.
• Cyrillic: Пацијент види крв.

Both are standard Serbian.

Because it is an international word of Latin origin, so it looks familiar in many European languages.

That is helpful for learners, but remember that even familiar-looking words still follow Serbian grammar. Here, pacijent behaves like a regular masculine noun in the singular nominative.
