The → grammatical case that marks a noun or pronoun typically expressing “possession” or “origin.”

In English, the genitive case of a noun is shown in writing by adding an s together with an appropriately positioned apostrophe or creating it by using the pronoun of.
For instance: “John’s house,” or “the house of John.” A → synthetic language would express the same idea by putting the name “John” in the genitive case.

Also called → possessive case.

Etymology (EN): From O.Fr. genitif or directly from L. (casus) genitivus “case expressing possession, source, or origin,” from genitivus “of or belonging to birth,” from genitus, p.p. of gignere “to beget, produce,” → generate; → case.

Etymology (PE): Dârešti, → possessive; kâté, → case..
