Noun declension

Nouns are declined for number with different models, depending on the last phoneme of the root.

Nouns, whose root ends in a consonant, add the so-called root vowel and change it:

Ø (-ɛ) → -e

Ø (-i) → -o

Ø (-u) → -o

Nouns, whose root ends in a vowel, change this last vowel. If the last vowel of the noun root is nasal, it keeps the nasalization while changing in the plural form. The general vowel changes are:

a → e	ã → ẽ
a → o	ã → õ	(Some nouns, regarded as irregular, undergo this change)
	ɛ̃ → ẽ
e → i	ẽ → ĩ
ə → e	ə̃ → ẽ
	ə̃ → õ	(Some nouns, regarded as irregular, undergo this change)
i → o	ĩ → õ
ɔ → o	ɔ̃ → õ
o → e	õ → ẽ
u → o	ũ → õ
y → i	ỹ → ĩ

Nouns are also declined in case by adding the following endings to the base form of the noun:

nominative	-h
accusative	-
genitive	-β
dative	-ž

Here is an example of a noun, whose root ends in a vowel: tõčah, village.

	romex		tõčah
	singular	plural
ergative	tõčah	tõčeh
absolutive	tõča	tõče
genitive	tõčaβ	tõčeβ
dative	tõčaž	tõčež

As for the rules, the endings for the instrumental and locative case cannot be added to a class I noun.
