In grammar, an oblique (abbreviated OBL; from Latin: casus obliquus) or objective case (abbr. OBJ) 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.
