The possessive case (abbreviated pos or poss) of a language is a grammatical case used to indicate a relationship of possession. It is not the same as the genitive case, which can express a wider range of relationships, though the two have similar meanings in many languages. The term "possessive case" is often used to refer to the "'s" morpheme, which is suffixed onto many nouns in English to denote possession. Calling it a case is arguably not strictly correct some grammarians contend that this affix is actually a clitic. By descent, however, the English usage does stem from a case ending, Old English -es.
