Cuêzi was the language of the ancient Cuzeians, an Eastern people who burst into Eretald in -375 Z.E. and dominated the Plain (Cēradānar) for more than a millennium. In particular, Cuêzi is the language of Cuzei itself, their kingdom in the Eärdur (Isrēica), with its capital at Eleisa. It was the first language of Eretald to be written; unusually, the writing system had no morphemographic stage, but began as an alphabet, under influence from the iliu. The modern Verdurian alphabet descends from the Cuêzi alphabet.
Cuzei was conquered by Caďinas in 1024, and actively supplanted by Caďinor. It was retained as a language of liturgy and scholarship by the Arašei, and in recent years it has been extensively studied by scholars wishing to read the Book of Eleď in the original.
It is a highly inflecting language; the unmarked word order is SOV.
- Nouns have three genders, two numbers, and six cases (nominative, accusative, genitive, dative, ablative, and instrumental).
- Adjectives fully agree with the nouns they modify, though there is an undeclined ‘combination form’ which increasingly replaces the inflected forms.
- Pronouns, unusually for an Eastern language, have gendered forms for all three singular persons (I, thou, he/she), as well as both inclusive and exclusive "we".
- Verbs are conjugated by number and person, and by active or passive voice, remote or definite mood, four tenses, perfect or imperfect aspect; there are also causative and inceptive forms, making 576 distinct lexical forms per verb.
