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
The vowels can also be analyzed as three mutated pairs of short and long vowels.
 * Allowable diphthongs are /aɪ/, /ɑːɪ/, /aɯ/, and /ɑːɯ/. The offglides are lowered somewhat in the standard (ex. [ae̯]), and the main vowel shifts back and up before phonetically voiceless consonants (ex. haij [hɜe̯tʃ], but haijo [hɜe̯dʒɜ]).

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 which follow codas are degeminated. ex. kantta*>kanta
 * Geminate consonants which follow long vowels are also degeminated. ex. kaatta*>kaata
 * Long vowels are shortened if there is another long vowel in the following syllable. ex. kaataa*>kataa

Stress
Stress in Iyachke takes the form of a high pitch on the syllable containing the antepenultimate mora, or a falling pitch if the stressed syllable contains more than one mora. Short vowels, syllable-final consonants, and geminate consonants contain one mora; short diphthongs and long vowels contain two; and long diphthongs contain three morae. Stress changes when suffixes are added, but if the number of morae in the suffixes would shift the stress off of the stem, then an extra mid-high pitched stress will be added to the first syllable of the stem.
 * ex. klaisso > kla-i-s-so > klaisso
 * yihaaj > yi-ha-a-j > yihaaj
 * yihaajki > yi-ha-a-j-ki > yihaajki
 * ngassini > nga-s-si-ni > ngassini
 * xokkiij > xo-k-ki-i-j > xokkiij

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.
 * The diphthongs, ai and ao, are written ayi and awo.

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

Punctuation
The script has four main punctuation marks.
 * Half stop: the half stop (labeled 'comma, colon' in the image) acts to set off lists and appositives, but not to separate members of a list, as a Latin comma is used for. It is always joined to the previous character.
 * Full stop: the full stop ends all sentences, even questions and exclamations. It is always joined to the previous character.
 * Parenthesis: The parenthesis are used to set off parenthetical information just like in the Latin script. They are optionally joined to the surrounding characters.
 * Apostrophe: the apostrophe is a diacritic used to indicate a contraction. It is placed in the same position as the length diacritic on the character immediately after the contraction.

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 singular or plural, but these are always optional.

The most common pluralizer 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. Components of a diphthong are treated as separate syllables and are broken up. The most common singularizer is -kko.
 * ex. klito /kʟ̝̊ɪtɜ/ > klitaani /kʟ̝̊ɪtɑːnɪ/ "languages"
 * ex. xokkiij /χɜkːiːS/ > xokkaani /χɜkːɑːnɪ/ "peoples"
 * ex. yijkohaon /jɪSkɜhaɯN/ > yijkohawaani /jɪSkɜhaɰɑːnɪ/ "students"

Cases
There are 20 cases, which are represented simply by suffixes. Suffixes with a long vowel shorten any long final syllable of a stem they are attached to.

Pronouns
Pronouns can be declined in any case. The third person singular distinguishes animate from inanimate, but this is purely natural gender, not grammatical gender which Iyachke lacks.

Noun congruence
Adjectives in Iyachke do not decline to match the case of the noun they are modifying. They instead decline for whether they describe the head noun in a phrase or a modifying noun. The head form is unmarked, and the dependent form has a suffix -n(o).
 * ex. tija sotiijngi klaisso "a soldier's short sword" vs. tijan sotiijngi klaisso "a short soldier's sword"

Negation
Adjectives can be negated with a prefixed lii-. ex. tija > liitija "not short", laasojo > lilaasojo "nonstandard", nin > liinin "bad"

Comparison
Adjectives also have comparative and superlative forms, which can combine with the negative.

Affix order
Preverb-3rd person Subject-Preroot moods-Root-Voice-Postroot moods-Subject-Object
 * ex. Kanso-wanki-taa-yi-lo? "Are you being forced to eat?"
 * Toolijin xanaa kosongoota ni-wao-xotti-taa-lo? "Would the key be given to me by the mayor?"
 * Saj-jaa-ngo-linta-yi-xa. "You will have to get through me."

Preverbs
Preverbs are prefixes which change the meaning of some roots. They are a discontinuous part of the verb stem.

Examples: saj "violently", ti "wavering", kasi "water"

Voice

 * Active (0)
 * Passive (wan)
 * Causative (ki)
 * Passive causative (wanki)
 * Applicatives can be formed with any case suffix in place of a voice affix.

Mood
Divided into pre- and post-root affixes. The two types cannot cooccur in applicative voices in the standard dialect. All postroot affixes become preroot in the applicative voice.

Preroot Moods: optative (ha), conditional (wao), desiderative (saan)

Postroot Moods: indicative (0), inferential (ngo), necessative (jaa), interrogative (taa)

Subject affixes

 * 1) 1st person- 0
 * 2) 2nd person- yi
 * 3) 3rd person- ni-
 * 4) reflexive- laj

Sentence-level order
The most neutral word order is Subject-Objects-Adverbs-Verb, but word order is quite free except for adjectives and adverbs. Subject and object pronouns are frequently dropped if the verb and/or context are enough for understanding.

Verb phrases
Verb phrases are generally left-branching. Nouns can be moved after the verb to call focus to them. 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"

Numbers
Most Aethos languages are base-8, due to the Aethos having one less finger per hand compared to Humans. The word for "number" is jaao.

Body parts

 * body: koonsaotta
 * thorax: kkillaj
 * abdomen: joolasi
 * head: haotinla
 * whiskers: kaasi
