The First Declension

The first declension encompasses primarily feminine nouns because they are characterized by certain endings and follow a specific pattern in their cases.

First Declension Endings:

 

Case Singular Plural
Nominative α / η αι
Genitive/Ablative ας / ης ῶν
Dative/Locative/Instrumental ᾳ / ῃ αις
Accusative αν / ην ας
Vocative

 

α / η αι

Nominative Singular: Ends in α or η. The naming case, typically used for the subject.

Genitive/Ablative Singular: ας or ης. Genitive expresses limitation. Ablative emphasizes source or separation.

Dative/Locative/Instrumental Singular: ᾳ or ῃ, used for indirect objects. It is the case of personal association.

Accusative Singular: αν or ην, the direct object form.

Vocative Singular: Usually identical to the nominative and used for direct address.

Plural Forms: The nominative and vocative plural end is αι, genitive/ablative is ῶν, dative/locative/instrumental is αις (for indirect objects), and accusative plural is ας.

The Article Agreement

Nouns take articles and adjectives that agree in gender, number, and case. Feminine nouns take the feminine forms of articles and adjectives, and masculine nouns take masculine forms.

Feminine Definite Article Forms:

Case Singular Plural
Nominative αἱ
Genitive/Ablative τῆς τῶν
Dative/Locative/Instrumental τῇ ταῖς
Accusative τήν τάς

 

Masculine Definite Article Forms:

Although the First Declension is primarily feminine, a few masculine nouns belong to this declension (e.g., μαθητής, “disciple”; νεανίας, “young man”).

The masculine article forms applied to First Declension nouns are as follows:

Case Singular Plural
Nominative οἱ
Genitive/Ablative τοῦ τῶν
