In linguistics, a possessive affix (from Latin: affixum possessivum) is an affix (usually suffix or prefix) attached to a noun to indicate its possessor, much in the manner of possessive adjectives.
Possessive affixes are found in many languages of the world. The World Atlas of Language Structures lists 642 languages with possessive suffixes, possessive prefixes, or both out of a total sample of 902 languages. Possessive suffixes are found in some Austronesian, Uralic, Altaic, Semitic, and Indo-European languages. Complicated systems are found in the Uralic languages; for example, Nenets has 27 (3×3×3) different types of forms distinguish the possessor (first-, second- or third-person), the number of possessors (singular, dual or plural) and the number of objects (singular, dual or plural). That allows Nenets-speakers to express the phrase "we two's many houses" in one word. Mayan languages and Nahuan languages also have possessive prefixes.
