English know hides three different relationships. Serbian знати covers facts, answers, and knowledge of how to do something; познавати means being acquainted with a person, place, or body of work; умети describes an acquired ability. Choosing correctly therefore depends first on the complement, then on tense, aspect, and what kind of knowledge is meant.
A compact present-tense map
All three verbs are imperfective states in their core meanings, but their present stems differ.
| Person | знати | познавати | умети |
|---|---|---|---|
| ја | знам | познајем | умем |
| ти | знаш | познајеш | умеш |
| он/она/оно | зна | познаје | уме |
| ми | знамо | познајемо | умемо |
| ви/Ви | знате | познајете | умете |
| они/оне/она | знају | познају | умеју |
The -јем in познајем and -еју in умеју are real parts of the forms; they are not optional pronunciation details. Negation is separate—не знам, не познајем, не умем—and questions can use да ли or the interrogative clitic ли.
Знам где је уговор, али не знам ко га је потписао.
I know where the contract is, but I don't know who signed it.
Да ли познајете некога ко поправља старе сатове?
Do you know anyone who repairs old clocks?
Не умем да вратим овај део на место.
I don't know how to put this part back in place.
Знати: facts, answers, languages, and know-how
Use знати with a noun denoting information (знати адресу, одговор, правило), a да-clause stating a fact, or an embedded question with где, када, зашто, како. Unlike English, Serbian does not insert an equivalent of do in questions or negation.
Она зна тачну адресу, па ћемо је питати.
She knows the exact address, so we'll ask her.
Знам да је састанак померен, али не знам за који дан.
I know the meeting has been moved, but I don't know to which day.
Знати can also mean “know how.” The ordinary Ekavian conversational pattern is знати + да + present, with the subject repeated in the finite verb after да. An infinitive is also standard: знам пливати, though it is more frequent in concise writing and in western Serbian usage than in everyday speech in much of Serbia.
Мој деда зна да поправи скоро сваки кућни апарат.
My grandfather knows how to repair almost any household appliance.
Знаш ли возити по снегу?
Do you know how to drive in snow? (standard infinitive; regionally more frequent in western usage)
With a language, знати српски normally means possessing knowledge of it. Говорити српски focuses more directly on speaking it.
Познавати: acquaintance and familiarity
Познавати takes a direct object in the accusative. With an animate masculine noun or name, that accusative has the genitive-like ending: познајем Марка, познајем новог директора. It means that the subject is acquainted with someone, or familiar with a place, system, or oeuvre—not merely that the subject knows one fact about it.
Познајем Јелену још из средње школе.
I've known Jelena since high school.
Добро познаје град и увек нађе мирнију улицу.
He knows the city well and always finds a quieter street.
Не познајем његов рад довољно добро да бих га оценила.
I don't know his work well enough to assess it. (female speaker)
English I know that doctor is ambiguous: it can mean acquaintance or knowledge about the doctor. Познавати makes acquaintance or sustained familiarity explicit.
Познајем ту лекарку, али не знам где сада ради.
I know that doctor personally, but I don't know where she works now.
Contemporary Serbian also permits знати + person, as in Знам га из школе “I know him from school.” It can overlap with познавати, especially in speech, so it is not an error by itself. Use познавати when acquaintance or familiarity is the point; use знати for facts about someone and in fixed or contextually established personal uses.
Neutral unstressed object pronouns use clitics: познајем га, не познајем је. In the past, the auxiliary is also a clitic and the l-participle agrees with the subject: познавала сам га for a female speaker, познавали смо га for a mixed or masculine plural subject.
Умети: acquired ability
Умети presents an action as a learned skill, competence, or knack. It is stronger than merely having an opportunity and often suggests that the subject can perform the action successfully. Compare умети with моћи, which usually marks possibility, permission, or ability under current circumstances.
Умем да направим тесто, али данас не могу да месим због повређене руке.
I know how to make dough, but today I can't knead because of my injured hand.
Она уме да објасни сложен проблем без непотребног жаргона.
She knows how to explain a complex problem without unnecessary jargon.
Like знати, умети permits both да + present and an infinitive. The да-construction is especially common in everyday Serbian; the infinitive is standard and often compact.
Нисам умео да одбијем, па сам прихватио још један задатак.
I didn't know how to say no, so I accepted another task. (male speaker)
The past умео/умела/умели... marks the subject's gender and number. The English form could does not tell you whether Serbian needs past моћи (“was able under those circumstances”) or умети (“possessed the skill”).
States versus acquiring knowledge
The three core verbs describe states and are imperfective. Serbian commonly uses other verbs for the event that creates the state:
| New event or process | Resulting state |
|---|---|
| сазнати / сазнавати — find out / be finding out | знати — know |
| упознати / упознавати — meet, get to know | познавати — know, be acquainted with |
| научити / учити — learn / study | знати or умети — know, know how |
These are semantic relatives, not interchangeable tense forms. A perfective present such as сазнам normally refers to a future, conditional, or repeated bounded event, not to a present state.
Кад сазнам тачан термин, одмах ћу ти јавити.
When I find out the exact time, I'll let you know immediately.
Упознала сам нову колегиницу јуче, али је још не познајем добро.
I met the new colleague yesterday, but I don't know her well yet. (female speaker)

Practice Tasks
Task 1: Choose the relationship
Complete four Serbian sentences for “I know the answer,” “I know Ana,” “I know how to sew,” and “I know that Ana sews.” Justify знати, познавати, or умети from the complement and intended meaning.
Task 2: Change state into event
Rewrite Знам вест, Познајем новог суседа, and Умем да возим as sentences about finding out, meeting, and learning. Then put each event in the past with correct l-participle agreement for a female speaker.
Common Mistakes
❌ Познајем где Милан ради.
Incorrect — познавати cannot introduce an embedded question about a fact.
✅ Знам где Милан ради.
I know where Milan works.
❌ Познајем да је рок у петак.
Incorrect — a factual да-clause is selected by знати, not познавати.
✅ Знам да је рок у петак.
I know the deadline is Friday.
❌ Умем одговор на прво питање.
Incorrect — an item of factual knowledge takes знати.
✅ Знам одговор на прво питање.
I know the answer to the first question.
❌ Она уме свира клавир.
Incorrect — умети cannot be followed by a bare finite verb copied from English syntax.
✅ Она уме да свира клавир, иако је све научила сама.
She knows how to play the piano, although she learned everything on her own.
❌ Јуче сам први пут познавао новог комшију.
Incorrect — a first meeting is a bounded event and requires упознати, not stative познавати.
✅ Јуче сам упознао новог комшију.
I met the new neighbor yesterday. (male speaker)
Key Takeaways
- Знати selects facts, answers, embedded questions, and know-how.
- Познавати + accusative expresses acquaintance or sustained familiarity.
- Умети + да + present/infinitive foregrounds learned competence; моћи foregrounds possibility or situational ability.
- Сазнати, упознати, and научити name changes of state, not simple perfective replacements for the three stative verbs.
