Noun declension

Nouns are declined for number by changing the last vowel of the noun root. The commonest change is the lengthening of the final vowel:

a → ā

e → ē

i → ī

o → ō

u → ū

If the last vowel of the noun root is already long in the singular, it undergoes a changing in height:

ā → ē

ē → ī

ī → ī

ō → ū

ū → ū

As it can be noticed, nouns whose root ends in -ī and -ū do not distinguish any different plural forms.

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

nominative	-x
accusative	-
genitive	-fu
dative	-šu
ablative	-ho
instrumental	-ma
locative	-va

Some examples are shown below: a class I noun, romex, father, and a class II noun, tōmex, house.

	romex		tōmex
	singular	plural	singular	plural
ergative	romex	romēx	tōmex	tōmēx
absolutive	rome	romē	tōme	tōmē
genitive	romefu	romēfu	tōmefu	tōmēfu
dative	romešu	romēšu	tōmešu	tōmēšu
dative	romeho	romēho	tōmeho	tōmēho
instrumental			tōmema	tōmēma
locative			tōmeva	tōmēva

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