The map of case overlaps
You have now met all seven cases one by one: nominativ, genitiv, dativ, akuzativ, vokativ, instrumental and lokativ, as Serbian grammars call them. And you have probably noticed something unsettling: a noun has fewer forms than there are case “slots” in its table. The same ending keeps doing duty for two, three, even five cases at once. This is not chaos or a gap in your memory: the forms coincide by rule, and the rules can be drawn as a map.
The lessons on the case forms promised this map more than once. Here it is. It introduces no new tables; they are all yours already, from “Genitive singular forms”, “Genitive plural”, “Dative forms”, “Accusative forms”, “Instrumental forms”, “Locative forms”, “Vocative forms” and “Adjective declension”. It answers two questions. First, which forms always coincide, so that there is no point learning them separately? Second, the practical one: when a form is ambiguous (and žene can be three cases), how do you tell which case you are looking at? The answer is simple: look not at the form itself but at its neighbours. The preposition, the verb, a number in front of the word and the words that agree with it almost always decide for you.
Dative = locative: one form, two jobs
The most reliable rule on the map: in nouns, the dative and the locative always coincide, in every gender, every declension and both numbers. On paper they are literally one form. The difference between them lies in the job they do, not in how they look.
The practical conclusion: do not learn the dative and the locative as two separate tables. Learn the dative and the locative comes free, and vice versa. What tells them apart is the context. The locative never appears without a preposition (u, na, o, po, pri), while the dative usually stands bare, after a verb with a recipient (dajem, kažem, pomažem), or comes with its own prepositions ka/prema. Compare Pišem bratu (“I’m writing to my brother”, dative) with Pišem o bratu (“I’m writing about my brother”, locative): the same form, and the preposition decides.
Adjectives and words like “this” and “that” behave the same way: novom gradu, toj ženi are both dative and locative. Personal pronouns are different. The short forms mi, ti, mu, joj, nam, vam, im exist only in the dative (Daj mi knjigu, “give me the book”); after a locative preposition you use the full form, which the dative shares: Pričaju o meni (“they are talking about me”), like Meni je hladno (“I’m cold”). In some words the locative also differs from the dative in its accent, but writing does not show it, and in the everyday speech of many people the difference has almost gone.
Neuters and inanimate masculines: nominative = accusative
The second big junction is the overlap of the nominative and the accusative. Here everything depends on animacy (whether the noun names a living being), which the lesson “Animacy” covered in detail. The rule fits on one line: in neuter nouns and inanimate masculines the accusative equals the nominative, while in animate masculines it equals the genitive.
The accusative singular hardly has an ending of its own: it borrows the nominative or the genitive, and only words in -a give it its own -u (ženu, ruku, tatu). In the neuter three cases coincide: selo is nominative, accusative and vocative at once (Ovo je selo, Vidim selo, and when you address a village, also selo).
The words that agree with the noun copy the rule: vidim stari grad, but vidim novog prijatelja. In personal pronouns the genitive and the accusative nearly always coincide: Nema ga (“he isn’t here”) and Vidim ga (“I see him”); only the full forms of “her” differ, nje (genitive) and nju (accusative). All of this is about the singular: in the plural, animacy changes nothing (Vidim ljude, “I see people”; vidim nove prijatelje, “I see new friends”).

The map of case overlaps
Cases of one word often look alike. Read the neighbours: preposition, verb, number, agreement.
Dative = locative, always
Nouns and adjectives (novom gradu). Locative only after a preposition; dative bare after “to whom?”, or after ka/prema: Pišem bratu / Pišem o bratu. Short mi, mu, joj: dative only; after a preposition, o meni.
Nominative = accusative: animacy decides
selo = Nom. = Acc. = Voc. Adjectives follow: stari grad, but novog prijatelja. Pronouns: Gen. = Acc. (ga; but nje / nju). Singular only: Vidim ljude.
The žene trap and the genitive plural
Plural: -ima / -ama for three cases
-ima in the 1st and 3rd declensions, -ama in the 2nd; likewise novim and nama, vama, njima. Šetamo gradovima: “around the cities”.
Most overlap: the 3rd declension
nema te stvari (Gen.), ne verujem toj stvari (Dat.), o toj stvari (Loc.), ove stvari su tu (Nom. plural), pet stvari (Gen. plural), kupujem stvari (Acc. plural). “This” helps: te / toj / tih.
Vocative
Its own form in the singular (ženo, studente, prijatelju); = Nom. in neuters (selo), the plural (Prijatelji!) and names in -o (Marko).
