The accusative case (abbreviated ACC) of a noun is the grammatical case used to mark the direct object of a transitive verb. The same case is used in many languages for the objects of (some or all) prepositions. It is a noun that is having something done to it, usually joined (such as in Latin) with the nominative case.
The English name "accusative" comes from the Latin accusativus, which, in turn, is a translation of the Greek . This word may also mean "causative", and this may have been the Greeks' intention in this name, but the sense of the Roman translation stuck and it is used in some other modern languages as the name of this case, for example in Russian ().
The accusative case is typical of early Indo-European languages and still exists in some of them (including Latin, Sanskrit, Greek, German, Polish, Russian), in the Finno-Ugric languages, and in Semitic languages (such as Arabic). Balto-Finnic languages, such as Finnish and Estonian, have two cases to mark objects, the accusative and the partitive case. In morphosyntactic alignment terms, both perform the accusative function, but the accusative object is telic, while the partitive is not.
Modern English almost entirely lacks declension in its nouns; pronouns, however, have an oblique case as in whom, them, and her, which merges the accusative and dative functions, and originates in old Germanic dative forms (see Declension in English).
In the sentence I see the car, the noun phrase the car is the direct object of the verb "see". In English, which has mostly lost the case system, the definite article and noun - "the car" - remain in the same form regardless of the grammatical role played by the words. One can correctly use "the car" as the subject of a sentence also: "The car is parked here."
In a declined language, the morphology of the article or noun changes in some way according to the grammatical role played by the noun in a given sentence. For example, in German, one possible translation of "the car" is der Wagen. This is the form in the nominative case, used for the subject of a sentence. If this article/noun pair is used as the object of a verb, it (usually) changes to the accusative case, which entails an article shift in German - Ich sehe den Wagen. In German, masculine nouns change their definite article from der to den in the accusative case.
The accusative case in Latin has minor differences from the accusative case in Proto-Indo-European (PIE). Nouns in the accusative case (accusativus) can be used
For the accusative endings, see Latin declensions.
The accusative case is used for the direct object in a sentence. The masculine forms for German articles, e.g., 'the', 'a/an', 'my', etc., change in the accusative case: they always end in -en. The feminine, neutral and plural forms do not change.
|Definite article (the)||den||die||das||die|
|Indefinite article (a/an)||einen||eine||ein|
For example, Hund (dog) is a masculine (der) word, so the article changes when used in the accusative case:
Some German pronouns also change in the accusative case.
The accusative case is also used after particular German prepositions. These include bis, durch, für, gegen, ohne, um, after which the accusative case is always used, and an, auf, hinter, in, neben, über, unter, vor, zwischen which can govern either the accusative or the dative. The latter prepositions take the accusative when motion or action is specified (being done into/onto the space), but take the dative when location is specified (being done in/on that space). These prepositions are also used in conjunction with certain verbs, in which case it is the verb in question which governs whether the accusative or dative should be used.
Adjective endings also change in the accusative case. Another factor that determines the endings of adjectives is whether the adjective is being used after a definite article (the), after an indefinite article (a/an) or without any article before the adjective (many green apples).
In German, the accusative case is also used for some adverbial expressions, mostly temporal ones, as in Diesen Abend bleibe ich daheim (This evening I'm staying at home), where diesen Abend is marked as accusative, although not a direct object.
In Russian, accusative is used not only to display the direct object of an action, but also to indicate the destination or goal of motion. It is also used with some prepositions. The prepositions ? and can both take accusative in situations where they are indicating the goal of a motion.
In fact Russian almost lost the real PIE accusative case, since only feminine nouns ending in 'a' have a distinct form. Other words use the genitive case in place of the accusative.
Esperanto grammar involves only two cases, a nominative and an accusative. The accusative is formed by the addition of -n to the nominative form, and is the case used for direct objects. Other objective functions, including dative functions are achieved with prepositions, all of which normally take the nominative case. Direction of motion can be expressed either by the accusative case, or by the preposition al (to) with the nominative.
In Ido the -n suffix is optional, as subject-verb-object order is assumed when it is not present. Note that this is sometimes done in Esperanto, especially by beginners, but it is considered incorrect while in Ido it is the norm.
According to traditional Finnish grammars, the accusative is the case of a total object, while the case of a partial object is the partitive. The accusative is identical either to the nominative or the genitive, except for personal pronouns and the personal interrogative pronoun kuka/ken, which have a special accusative form ending in -t.
The major new Finnish grammar, Iso suomen kielioppi, breaks with the traditional classification to limit the accusative case to the special case of the personal pronouns and kuka/ken. The new grammar considers other total objects as being in the nominative or genitive case.

The accusative case is called in Arabic (an-na?b, and it has many other uses in addition to marking the object of a verb.

In Japanese, the accusative case is marked by placing ? (wo, pronounced /o?/) between the noun and the verb.
