❓ What are cases?
English already has cases — but only in pronouns. I see him / He sees me: scramble the word order and the shape of the word still tells you who does what. That's a case system. Everywhere else, English gave up on it and uses prepositions and word order instead.
Serbian never gave up. It extends the I / me / my idea to every noun: the ending of the word encodes its job in the sentence. There are seven jobs — seven padeži. Learn the seven jobs and the endings, and the case system is done. Everything else is vocabulary.
Bonus: because the ending carries the meaning, word order is free. Vidim brata and Brata vidim both mean "I see the brother" — the -a on brata marks him as the one seen, wherever he sits in the sentence.
Suggested learning order. Native English speakers usually do best when cases are introduced as they are needed, not in the traditional textbook order.
Nom → Acc → Gen → Dat/Loc → Ins → Voc
The shapes, jobs and matrix below are arranged in that order.
🔀 One word, seven shapes The same noun — brat, "brother" — in each of the seven roles. English reaches the same meaning with prepositions and word order.
🛠️ The seven jobs Each case answers one question and maps to something English already does. Learn the job, not the name.
The subject — English I, he, who
- Whoever does the verb: Kafa je vruća. — The coffee is hot.
- After "to be": On je student.
- The dictionary form. Never used with a preposition.
The direct hit — English me, him, whom
- The direct object: Vidim brata. Čitam knjigu.
- Motion toward, with
uinto ·naonto ·zafor ·krozthrough: Idem u grad. - Masculine animate singular: Acc takes the Gen shape (brata). Inanimate: Acc = Nom (grad). Singular only — the plural drops the split.
Of, from, none — English of, 's
- Possession: knjiga brata — my brother's book.
- Absence: Nema vode. — There's no water.
- Quantities: čaša vode — a glass of water; and after numbers (dva brata, pet braće).
- The workhorse case: most prepositions of source or absence take it —
odfrom ·izout of ·dountil ·bezwithout ·kodat someone's.
To / for someone — English (to) him
- The recipient: Dajem bratu knjigu. — I give my brother a book. English keeps this in pronouns: I gave him a book.
- Direction toward: idem kući — going home; with
ka/k,prematoward. - The feeler: Meni je hladno. — I'm cold (lit. "to me it is cold").
About / at a place — English in, on, at, about
- Location, no motion: u gradu — in the city.
- Topic of speech or thought: Pričam o bratu.
- Always with a preposition —
uin ·naon ·oabout ·poaround ·prinear. There is no bare Lokativ. - Same shape as Dativ — the preposition is the giveaway.
With / by means of — English with, by
- The tool: pišem olovkom — I write with a pen.
- The companion (add
sa): idem sa bratom. - Transport: idem autobusom — by bus.
- English splits tool and companion across contexts; Serbian merges them into one case —
saappears only with the companion.
Calling out — no English form
- Direct address, set off by commas: Marko, dođi! — Marko, come!
- English reuses the plain noun here; Serbian gives it an ending: Petar → Petre!, brat → brate!
- Names already ending in -o/-e (Marko, Mile, Ivo) stay unchanged.
⚠️ The three traps These cause 90% of case mistakes. Everything else follows from the matrix below.
1 · Motion vs location — same preposition, two cases
With u and na: if something is moving toward, use Akuzativ; if it's already there, use Lokativ. English marks the same split with different prepositions — into vs in. Idem na posao (to work) vs Radim na poslu (at work).
2 · Animate masculine Akuzativ = Genitiv
For masculine nouns in the singular, the Akuzativ borrows the Genitiv ending when the noun is alive (brata) and the Nominativ when it isn't (grad). This is why vidim brata looks identical to knjiga brata. Context, not form, tells possession from object. The plural ignores the rule: vidim gradove, braću.
3 · Dativ and Lokativ are identical — the preposition decides
The forms are the same for every gender. Don't try to tell them apart by shape: no preposition → Dativ (to/for someone); preposition u/na/o/po/pri → Lokativ (at/about). One form, two labels.
📋 The endings Singular only. Memorize this 3 × 7 matrix and the vast majority of nouns fall into place.
