 Nouns and adjectives have two cases, nominative/oblique and accusative/allative, and two numbers, singular and plural; the adjectival form of personal pronouns behaves like a genitive case.Adjectives generally agree with nouns in case and number.In addition to indicating direct objects, the accusative/allative case is used with nouns, adjectives and adverbs for showing the destination of a motion, or for replacing certain prepositions; the nominative/oblique is used in all other situations.
