In linguistics, possession is an asymmetric relationship between two constituents, the referent of one of which (the possessor) in some sense possesses (owns, has as a part, rules over, etc.) the referent of the other (the possessed).
Possession may be marked in many ways, such as simple juxtaposition of nouns, possessive case, possessed case, construct state (as in Arabic and Nêlêmwa), or adpositions (possessive suffixes, possessive adjectives). For example, English uses a possessive clitic, 's; a preposition, of; and adjectives, my, your, his, her, etc.
