The standard first-declension nouns were described here. The first variant of the first-declension pattern is a short alpha found in the nominative, vocative and the accusative singular.

This group of first declension nouns have nominatives that end in -α, whether the stem ends in ε, ι or ρ or not. First declension nouns in -α are declined with the following endings:

		after anything but ε, ι or ρ			after ε, ι or ρ
		Singular	Plural		Singular	Plural
Nominative (nom.)		-α	-αι		-α	-αι
Genitive (gen.)		-ης	-ῶν		-ᾱς	-ῶν
Dative (dat.)		-ῃ	-αις		-ᾱͅ	-αις
Accusative (acc.)		-αν	-ᾱς		-αν	-ᾱς
Vocative (voc.)		-α	-αι		-α	-αι

* As with other nouns, take the genitive singular form (which can be found in a proper dictionary entry) and remove the ending; to that stem add the appropriate ending for the case and number required.

Differences from standard first-declension nouns can be seen in blue. Otherwise, the rules for accentuation remain consistent with other first-declension nouns.
