Ergative case (abbreviated as ERG) is the grammatical case that identifies the noun as the agent (subject) of a transitive verb in ergative-absolutive languages. In Nûrlâm the typical ergative case ending is -irz for declension class I, and -rz for declension class II. Because pronouns are usually merged with verb, ergative case is not used with them, or on may say their ergative form is the same as absolutive. Ergative case is actively used only in Archaic Nûrlâm, while in Standard language it is used only in passive-like constructions. In Modern Nûrlâm it is totally absent. See article about ergative alignment for more information and examples. In Standard and Modern Nûrlâm function of ergative case to mark agent of action were taken by similar Instrumental case together with passive participles.
