Iyachke

General
Iyachke (/ɪjátʃki/, natively Laasojo Yihaajki klito "Standard Iyach language", colloquially Yihaa'to or Yi'to) is a language spoken by the Aethos (Xokkiij Jiyaata) on the Isle of Iyach (Yihaaj) on the planet Aetho (Jiyaa).

Consonants

 * Voiceless consonants are voiced intervocallically or after /N/.
 * /n/, /ŋ/, /t/, /k/, /s/, and /ɺ/ may be geminated in all dialects. /tʃ/ may be geminated in the standard dialect.
 * Geminate /ɺ/ is typically not flapped, though the actual pronunciation varies dialectally. In the standard, it is [ɭː].
 * /h/ can be dropped in colloquial speech.

Vowels

 * Allowable diphthongs are /aɪ/, /ɑːɪ/, /aɯ/, and /ɑːɯ/. The offglides are lowered somewhat in the standard (ex. [aɛ̯]), and the main vowel shifts back and up before phonetically voiceless consonants (ex. aij [ʌɛ̯tʃ], but aijo [aɛ̯dʒɜ]).

Phonotactics
CV(N, S, NS)
 * /N/ is a homorganic nasal. On the end of words it can be /n/ or /ŋ/, according to the dialect.
 * /S/ is a fricative which differs depending on the dialect. In the standard, it is pronounced [tʃ].
 * Long /t/, /k/, /s/, and /ɺ/ CAN begin words. ex. llanti [ɭːandɪ] "feathers"
 * Geminate consonants cannot follow codas. ex. kantta*
 * Long vowels cannot be followed by geminate consonants. ex. kaatta*
 * Two long vowels cannot be in adjacent syllables. ex. kaataa*

Native Script
The native script for Iyachke is a syllabary, shown on the right. The Iyachke word for a writing system is ngassini.

Interesting features

 * It shares some features with the Arabic alphabet on a design level. It is a cursive script so letters are joined with a baseline, which is semi-optional in handwritten texts.
 * Many characters look quite similar, being distinguished by meaningless marks.
 * Diphthongs are written ayi and awo for ai and ao.

Writing Direction
The script is written left-to-right, top-to-bottom, like English.

Collation
There are three common orders for the characters: phonetic, graphic, and poetic.
 * Phonetic: yi, yo, ya, wo, wa, li, lo, la, ho, ha, si, so, sa, ni, no, na, ji, jo, ja, ki, ko, ka, ngi, ngo, nga, ti, to, ta, xo, xa, kli, klo, kla, j, n
 * Graphic: yi, ngo, wo, wa, la, kli, ji, sa, ki, si, yo, ko, li, ta, ya, ti, ho, xo, ni, j, xa, lo, klo, n, jo, to, no, ka, nga, so, kla, na, ha, ja, ngi

Nouns
Nouns decline for number and case.

Number
Noun roots are inherently transnumeral, that is, whether they are singular or plural must be determined from context. However, suffixes can be applied which make a noun plural, but these are always optional. The most common of these is -Qaa(i)ni, where the Q represents a removal of the rime of the last syllable and where the (i) is only found in rural areas.
 * ex. klito /kʟ̝̊ɪtɜ/ > klitaani /kʟ̝̊ɪtɑːnɪ/ "languages"
 * ex. xokkiij /χɜkːiːS/ > xokkaani /χɜkːɑːnɪ/ "peoples"
 * ex. yijkohaon /jɪSkɜhaɯN/ > yijkohawaani /jɪSkɜhɑːnɪ/

Sentence-level order

Verb phrases
Verb phrases are generally right-branching, with the exception that adverbs are placed before the verb. Nouns declined to modify the whole clause are placed after any other adverbs.

Noun phrases
Noun phrases are purely left-branching, with the quirk that nouns declined to modify other nouns are placed after any adjectives. ex. Laasojo Yihaajki klito "Standard Iyach-in language"
