Hindi-Urdu (Hindustani) has three noun cases, the nominative, oblique, and vocative cases. The vocative case is now obsolete (but still used in certain regions[citation needed]) and the oblique case doubles as the vocative case. The pronoun cases in Hindi-Urdu are the nominative, ergative, accusative, dative, and two oblique cases.[1][2] The case forms which do not exist for certain pronouns are constructed using primary postpositions (or other grammatical particles) and the oblique case (shown in parentheses in the table below).
