Greek adjectives must agree with the noun they describe in gender, number and case however they do not all follow the same pattern of endings. An in-depth knowledge of all these endings is not required however one must be aware of the various forms existing since it can come in helpful when deciphering a sentence.
There are three main sets of endings for adjectives, all corresponding to relevant noun endings.
The 2-1-2 DeclensionsEdit
This comes in two forms, irregular and regular.
In the regular form the endings are the same as the 2nd declension for the masculine and neuter nouns whilst the feminine endings follow the pattern of 1st declension feminine nouns. This gives it the name 2-1-2 for masculine, feminine and neutered.
The irregular form is exactly the same in the plural however in the singular follows a slightly bizarre pattern where the genitive and dative are exactly the same as in the regular form however the nominative and accusative have no real correlation as they follow the pattern of third declension nouns.
The 3-1-3 DeclensionEdit
The masculine and neuter adjectives have the third declension endings whilst the feminine form follows the first declension ending with the addition of an epsilon between the stem and the ending.
The 3-3 DeclensionEdit
This is where the masc and fem are the same and, along with the neuter, follow the third declension endings.
