Greek adjectives agree with the nouns they modify in gender, number, and case. They can appear in attributive position (with article) or predicate position (without).
Attributive: ὁ ἀγαθὸς ἀνήρ or ὁ ἀνὴρ ὁ ἀγαθός ("the good man") Predicate: ἀγαθὸς ὁ ἀνήρ ("the man is good")
Most adjectives follow two patterns: • Three-ending (-ος, -η/-α, -ον): separate feminine forms • Two-ending (-ος, -ον): masculine and feminine share forms
Comparison: • Comparative: -τερος, -τερα, -τερον or -ίων, -ιον • Superlative: -τατος, -τατη, -τατον or -ιστος, -ίστη, -ιστον
