In the animate gender, an "-i-" is inserted between the stem and the case ending. In hieroglyphic Luwian, the particle "-sa/-za" is added to the nominative/accusative inanimate case ending. In the genitive case, cuneiform and hieroglyphic Luwian differ sharply from each other. In cuneiform Luwian the possessive suffix "-assa" is used for the genitive singular and "-assanz-" is used for the genitive plural. In hieroglyphic Luwian, as in Hittite, the classical Indo-European suffixes "-as" for the genitive singular and "-an" for the plural are used. The special form of possessive adjectives with a plural possessor is restricted to Kizzuwatna Luwian and probably represents a calque from Hurrian.
