Oblique case

In grammar, an oblique (abbreviated ; from ) or objective case (abbr. ) is a nominal case other than the nominative case, and sometimes, the vocative.
A noun or pronoun in the oblique case can generally appear in any role except as subject, for which the nominative case is used. The term "objective case" is generally preferred by modern English grammarians, where it supplanted Old English's dative and accusative.
When the two terms are contrasted, they differ in the ability of a word in the oblique case to function as a possessive attributive; whether English has an oblique rather than an objective case then depends on how "proper" or widespread one considers the dialects where such usage is employed.
An oblique case often contrasts with an unmarked case, as in English oblique "him and "them vs. nominative "he" and "they". However, the term "oblique" is also used for languages without a nominative case, such as ergative–absolutive languages; in the Northwest Caucasian languages, for example, the oblique-case marker serves to mark the ergative, dative, and applicative case roles, contrasting with the absolutive case, which is unmarked.
Hindustani.
Hindustani (Hindi and Urdu) nouns and pronouns decline for an oblique case which exclusively serves to mark the grammatical case roles using the case-marking postpositions. The nominative and oblique cases for pronouns are shown in the tables below:
There are six noun declension patterns in Hindustani. They are mentioned in the table below:
Note: -ø "means anything other than -ā, -i, and -ī for masculine and anything other than -i/ī for feminine."
The oblique case is used exclusively with these 8 case-marking postpositions. Out of these 8 postpositions, the genitive and semblative postpositions decline to agree with the gender, number, and case of the object it shows possession of, or the subject it semblance of to something/someone.
Bulgarian.
Bulgarian, an analytic Slavic language, also has an oblique case form for pronouns:
Dative role:
English.
An objective case is marked on the English personal pronouns and as such serves the role of the accusative and dative cases that other Indo-European languages employ. These forms are often called object pronouns. They serve a variety of grammatical functions which they would not in languages that differentiate the two. An example using first person singular objective pronoun me:
The pronoun "me" is not inflected differently in any of these uses; it is used for all grammatical relationships except the genitive case of possession (in standard English) and a non-disjunctive nominative case as the subject.
French.
Old French had a nominative case and an oblique case, called and respectively.
In Modern French, the two cases have mostly merged and the "cas régime" has survived for the majority of nouns. For example, the word ""conte" (tale)":
In some cases, both the "cas sujet" and "cas régime" of one noun have survived but produced two nouns in Modern French with different meanings. Example today's means "friend" and is "companion", but in Old French these were different declensions of the same noun.
Kurdish.
Kurdish has an oblique for pronouns, objects, and for objects of Izafe constructs.
