Serbo-Croatian grammar

Serbo-Croatian is a South Slavic language that, like most other Slavic languages, has an extensive system of inflection. This article describes exclusively the grammar of the Shtokavian dialect, which is a part of the South Slavic dialect continuum and the basis for the Bosnian, Croatian, Montenegrin, and Serbian standard variants of Serbo-Croatian. "An examination of all the major 'levels' of language shows that BCS is clearly a single language with a single grammatical system."

Pronouns, nouns, adjectives and some numerals decline (change the word ending to reflect case, the grammatical category and function) whereas verbs conjugate for person and tense. As in other Slavic languages, the basic word order is subject–verb–object (SVO), but the declensions show sentence structure and so word order is not as important as in more analytic languages, such as English or Chinese. Deviations from the standard SVO order are stylistically marked and may be employed to convey a particular emphasis, mood or overall tone, according to the intentions of the speaker or writer. Often, such deviations will sound literary, poetical or archaic.

Nouns have three grammatical genders (masculine, feminine and neuter) that correspond, to a certain extent, with the word ending. Accordingly, most nouns with -a are feminine, -o and -e neuter, and the rest mostly masculine but with some feminine. The grammatical gender of a noun affects the morphology of other parts of speech (adjectives, pronouns, and verbs) attached to it. Nouns are declined into seven cases: nominative, genitive, dative, accusative, vocative, locative, and instrumental, albeit with considerable syncretism (overlap) especially in the plural.
