   19. Cases of Nouns are six: Nominative, Genitive, Dative, Accusative, Vocative, and Ablative. As in the Latin and Greek languages, these cases are derived from the Nominative by certain rules of inflection; the Nominative being the root of all the other cases, is termed the direct case, the others are called oblique cases.
