THE NOMINATIVE CASE PLURAL OF THE NOUNS OF THE
1st- 5th DECLENSIONS
To form the Nominative plural of nouns it is necessary:
1. to know the Dictionary form of the noun in order to be able to define the declension and gender of the term;
2. to be able to single out the base of the noun in order to attach the corresponding ending in the Nominative plural to it. Memorize the noun endings of all five declensions in the Nominative plural:
