Overview
Serbian adjectives have gender, number and case (adjective-declension-b1) plus a definiteness distinction inherited from Common Slavic: an indefinite and a definite form. In the modern language this survives as a fully productive, meaning-bearing choice in exactly one cell of the paradigm - masculine nominative singular - plus a fading trace in the masculine/neuter genitive and dative singular; everywhere else the definite form has generalized.
basic-adjectives-a1 taught нов as one word, and adjective-declension-b1's case table already used the definite endings throughout (новог, новом, новим) without naming the choice. This lesson names it explicitly and gives the rule for each form.
Where the contrast survives: masculine nominative and short genitive/dative
The clearest, fully alive pair is masculine nominative singular: indefinite нов has no ending, definite нови adds -и. Every adjective works this way, including irregular fleeting-a ones from basic-adjectives-a1 - indefinite добар, definite добри.
Genitive and dative/locative singular (masc./neut.) also have a historic short indefinite form - genitive нова, dative/locative нову - beside the definite long forms adjective-declension-b1 already gave as default, новог(а) and новом(е). In modern spoken Serbian the long forms have largely spread into these cells even when the meaning is indefinite, so treat the short pair as something to recognize in reading, not something to actively produce.
Usage: predicative short form, attributive long form
The core rule: an adjective in predicate position - after је/су, describing the subject - takes the indefinite short form: Стан је нов. An attributive adjective naming a specific, already-known referent takes the definite long form: нови стан у који смо се уселили names one particular apartment, not any new apartment.
An attributive adjective that introduces something as one instance of its kind, not a known referent, stays indefinite: Купио сам нов ауто. (some new car, first mention) versus Купио сам нови ауто о коме смо причали. (the specific car already discussed).
Always-definite categories and fossilized short forms
Some adjective-like words are always definite in form regardless of context: superlatives (највећи, најлепши - comparison-of-adjectives-a2), ordinal numbers (први, други, трећи - ordinal-numbers-a2), and, in practice, any adjective after a demonstrative or possessive (овај нови сто, мој нови телефон) - the demonstrative or possessive already particularizes the noun, so the adjective agrees and takes the long form too.
A handful of indefinite short forms have frozen into fixed phrases and greetings, immune to the rule above: Добар дан!, Срећан пут!, Лаку ноћ! These are memorized as whole phrases, not built from the usage rule.
Tables
| Case | Indefinite (short) | Definite (long) |
|---|---|---|
| номинатив | нов | нови |
| генитив | нова | новог(а) |
| датив/локатив | нову | новом(е) |
Examples
Compared with…
English marks (in)definiteness on the noun phrase with articles - a new car vs. the new car - never on the adjective itself, and has no morphological definite/indefinite adjective forms at all. The a/the split is nonetheless the closest conceptual handle: indefinite нов tends to answer to „a new…“, definite нови to „the new…“, even though Serbian has no articles and encodes the distinction on the adjective's own ending instead.
Common mistakes
Tips & exceptions
- Listen first to the masculine nominative singular ending - no ending means indefinite, -и means definite. This is the one cell of the whole paradigm where the choice is still fully alive and meaning-bearing.
- If a demonstrative, possessive, superlative or ordinal is already doing the work of pointing at a specific thing, default the adjective after it to the definite long form.
- Beyond masculine nominative singular, modern spoken Serbian mostly uses the long definite ending regardless of meaning - recognize the short genitive/dative pair in reading, but don't feel obliged to produce it yourself.
- Fossilized indefinite short forms survive frozen inside set phrases and greetings no matter what the usage rule above would predict: „Добар дан!“, „Срећан пут!“, „Лаку ноћ!“
- A handful of common adjectives, such as мали (already flagged in basic-adjectives-a1), are normally used only in the long/definite form in everyday speech - the short indefinite counterpart barely occurs at all.
- Feminine and neuter singular show almost no living contrast - both genders generalized the long/definite endings long ago, so the productive, meaning-bearing choice described in this lesson is really a masculine-only phenomenon.
