Adjectives

Adjectives decline, agreeing in case, number, and gender. Nominative singular male is the dictionary form. Most end –ος.

The general pattern is that adjectives decline the same way as the nouns. For example, όμορφος or beautiful:

Adjectives with a vowel before the ending, like νέος or new, use –α in the feminine singular:

Some that end –κός or –χός use –ια for the feminine singular, although it seems that you can also use the usual –η.
