Étirian

Étirian (étirana [ɛtɪrænə]) is a macrolanguage spoken by the people of the fictional continent of Étir. It is one of only a few languages spoken on the continent. The origin of the language is unknown, and dates before the Fall; however, it is known that the language began to diverge after survivors speaking the language were isolated after the fall in discrete geographical regions, leaving them to evolve their own dialects, which they still have today. A person who speaks Étirian is referred to as an Étirian in English, or an étirla in Étirian.

Every city on the continent uses the language in an official capacity; however, it is the dialect of the language used that differs from region to region. The 2000 Cassal census found there to be over 500 million primary speakers of the language across Étir, and 200 million primary speakers of the Iperion dialect of the language. Only 50 thousand people speak Étirian as a secondary language.

Classification and Dialects
Étirian is an a posteriori conlang that, if it did not exist only in a fantasy universe, could be considered to be a Romance language.

Phonotactics

 * Syllables should contain a nucleus.
 * If a portmanteau word has two accented vowels adjacent to each other, only the first vowel keeps the accent (this is due to necessity within the writing system).
 * Syllables should contain at least one vowel.
 * A word cannot end in /ɾ/.
 * The diphthong /ks/ covers two syllables (/k.s/) when used in a word.
 * An infinitive of a verb must have at least two syllables.
 * The 're' ending of an infinitive verb must not be preceded by an 'a'.

Writing System
Étirian uses an abugida writing system, but it can be written in a Latin alphabet for real-world convenience.
