Greek nouns

Greek first declension has two basic classes of feminine endings and one basic class of masculine endings, distinguished by their original nominative singular: long ''-ā'', short ''-(y)ă'', long ''-ās''. But besides the nominative and accusative singular of feminines, and nominative, genitive, and vocative singular of masculines, forms are the same between subclasses. In the Attic dialect, an ''ā''-''ē'' split divides each class into two subclasses: nouns with ᾱ and nouns with η. By contrast, other dialects tend to generalize the vowel one way or the other — Ionic has only ''ē'', and Doric and

have only ''ā''.

Greek adjectives

The feminine of first- and second-declension adjectives uses the ''-ā'' class of the first declension: * ''-os, -ā/ē, -on'' First- and third-declension adjectives, including participles in ''-nt-'', use the ''-(y)ă'' class. Here are examples of this class, which is complex because of sound changes involving the ''y'' (see Ancient Greek nouns: short a): *''-us, -eia, -u'' *''-ās, -aina, -an'' *''-ōn, -ousa, -on'' *''-ās, -āsa, -an'' *''-eis, -eisa, -en''
