Tirean

Basic Grammar
Tirean has five cases: nominative, accusative, dative, genitive and vocative. The noun is declined according to these cases and number. Nouns themselves are split into three groups. The declension of the first group is as follows:

To the first group belong all nouns (and names) which end in -os.

The second group is split into two sub groups, which vary only slightly, mostly owing to different formations of the plural:

To this group belong all nouns ending in -as, -acc, -aol or -a.

To this group belong all nouns ending in -add, -ad.

Accusative
The accusative is only used to denote a subject. It is easily recognised, since all its forms end in -n.

Dative
The dative is used with the meaning 'for, towards, by' and is frequently found after prepositions.

Genitive
The genitive is formed in Tirean by a process of umlaut and is distinguishable by the ending '''-ar. '''The main vowel of the noun is changed according to a set of rules, which are as follows:

The Definite Article
Tirean has no indefinite article. When a word stands on its own it is counted as indefinite. When the definite article is used then it is declined instead of the verb. The definite article is the same for all three groups.

Thus we have 'sulas tarar' 'a wolf's eye' but 'an sulas einar toros' 'the eye of the wolf'
