Accusative case in the context of Case endings

A grammatical case is a category of nouns and noun modifiers (determiners, adjectives, participles, and numerals) that corresponds to one or more potential grammatical functions for a nominal group in a wording. In various languages, nominal groups consisting of a noun and its modifiers belong to one of a few such categories. For instance, in English, one says I see them and they see me: the nominative pronouns I / they represent the perceiver, and the accusative pronouns me/them represent the phenomenon perceived. Here, nominative and accusative are cases, that is, categories of pronouns corresponding to the functions they have in representation.

English has largely lost its inflected case system but personal pronouns still have three cases, which are simplified forms of the nominative, accusative (including functions formerly handled by the dative), and genitive cases. They are used with personal pronouns: subjective case (I, you, he, she, it, we, they, who, whoever), objective case (me, you, him, her, it, us, them, whom, whomever), and possessive case (my, mine; your, yours; his; her, hers; its; our, ours; their, theirs; whose; whosever). Forms such as I, he, and we are used for the subject ("I kicked John"), and forms such as me, him, and us are used for the object ("John kicked me").

In linguistic typology, ergative–absolutive alignment is a type of morphosyntactic alignment in which the subject of an intransitive verb behaves like the object of a transitive verb, and differently from the subject of a transitive verb. Examples include Basque, Georgian, Mayan, Tibetan, Sumerian, and certain Indo-European languages (such as Pashto and the Kurdish languages and many Indo-Aryan languages like Hindustani). It has also been attributed to the Semitic modern Aramaic (also called Neo-Aramaic) languages. Ergative languages are classified into two groups: those that are morphologically ergative but syntactically behave as accusative (for instance, Basque, Pashto and Urdu) and those that, on top of being ergative morphologically, also show ergativity in syntax. Languages that belong to the former group are more numerous than those to the latter.

The ergative-absolutive alignment is in contrast to nominative–accusative alignment, which is observed in English and most other Indo-European languages, where the single argument of an intransitive verb ("She" in the sentence "She walks") behaves grammatically like the agent (subject) of a transitive verb ("She" in the sentence "She finds it") but different from the object of a transitive verb ("her" in the sentence "He likes her"). When ergative–absolutive alignment is coded by grammatical case, the case used for the single argument of an intransitive verb and the object of a transitive verb is the absolutive, and the case used for the agent of a transitive verb is the ergative. In nominative-accusative languages, the case for the single argument of an intransitive verb and the agent of a transitive verb is the nominative, while the case for the direct object of a transitive verb is the accusative.

In linguistics, declension (verb: to decline) is the changing of the form of a word, generally to express its syntactic function in the sentence by way of an inflection. Declension may apply to nouns, pronouns, adjectives, adverbs, and determiners. It serves to indicate number (e.g. singular, dual, plural), case (e.g. nominative, accusative, genitive, or dative), gender (e.g. masculine, feminine, or neuter), and a number of other grammatical categories. Inflectional change of verbs is called conjugation.

Declension occurs in many languages. It is an important aspect of language families like Quechuan (i.e., languages native to the Andes), Indo-European (e.g. German, Icelandic, Irish, Lithuanian and Latvian, Slavic, Sanskrit, Latin, Ancient and Modern Greek, Albanian, Romanian, Kurdish, and Modern Armenian), Bantu (e.g. Swahili, Zulu, Kikuyu), Semitic (e.g. Modern Standard Arabic), Finno-Ugric (e.g. Hungarian, Finnish, Estonian), and Turkic (e.g. Turkish).

The phrase law of the land is a legal term, equivalent to the Latin lex terrae, or legem terrae in the accusative case. It refers to all of the laws in force within a country or region, including statute law and case-made law.

The word thou (/ðaʊ/) is a second-person singular pronoun in English. It is now largely archaic, having been replaced in most contexts by the word you, although it remains in use in parts of Northern England and in Scots (/ðu:/). Thou is the nominative form; the oblique/objective form is thee (functioning as both accusative and dative); the possessive is thy (adjective) or thine (as an adjective before a vowel or as a possessive pronoun); and the reflexive is thyself. When thou is the grammatical subject of a finite verb in the indicative mood, the verb form typically ends in -(e)st (e.g., "thou goest", "thou do(e)st"), but in some cases just -t (e.g., "thou art"; "thou shalt").

Originally, thou (in Old English: þū, pronounced [θuː]) was simply the singular counterpart to the plural pronoun ye, derived from an ancient Indo-European root. In Middle English, thou was sometimes represented with a scribal abbreviation that put a small "u" over the letter thorn: þͧ (later, in printing presses that lacked this letter, this abbreviation was sometimes rendered as yͧ). Starting in the 1300s, thou and thee were used to express familiarity, formality, or contempt, for addressing strangers, superiors, or inferiors, or in situations when indicating singularity to avoid confusion was needed; concurrently, the plural forms, ye and you, began to also be used for singular: typically for addressing rulers, superiors, equals, inferiors, parents, younger persons, and significant others. In the 17th century, thou fell into disuse in the standard language, often regarded as impolite, but persisted, sometimes in an altered form, in regional dialects of England and Scotland, as well as in the language of such religious groups as the Society of Friends. The use of the pronoun is also still present in Christian prayer and in poetry.

In grammar, a ditransitive (or bitransitive) verb is a transitive verb whose contextual use corresponds to a subject and two objects which refer to a theme and a recipient. According to certain linguistics considerations, these objects may be called direct and indirect, or primary and secondary. This is in contrast to monotransitive verbs, whose contextual use corresponds to only one object.

In languages which mark grammatical case, it is common to differentiate the objects of a ditransitive verb using, for example, the accusative case for the direct object, and the dative case for the indirect object (but this morphological alignment is not unique; see below). In languages without morphological case (such as English for the most part) the objects are distinguished by word order or context.
