I still haven’t finished doodling characters for the Inyuna syllabary, BUT I am already working out *how* this writing system will work after the absolute hellpit (they’re not actually that bad) of sound changes Inyuna has gone through, so here’s a Step-by-step Guide to Write the Word “Nāhuma”!
First and foremost, we must look at the OI (Old Inyuna) form of the word, i.e. *(hi)n(a)-anka-huu-ban. The first syllable /hi/ will be dropped over time, so we can ignore it, whereas that /a/ will be assimilated by the root *anka, so what we’re actually trying to write is *nankahuuban, which in the syllabary can be pretty easily represented as <na-an-ka-hu-u-ba-an>
Now, the first sound change to come along and ruin everything is syncope. Luckily, in this case it only affects one syllable, turning *nankahuuban into *nankhuuban. To represent this, in the writing system we will add a little accent-like diacritic on the syllable <ka> to suppress its vowel, giving us <na-an-kà-hu-u-ba-an>
Next up is loss of vowel length, which is as simple as removing the lengthening <u> from the spelling: <na-an-kà-hu-u-ba-an> -> <na-an-kà-hu-ba-an>
Then, the so-called “nasal vowels” (could either be actual nasal vowels or oral vowels followed by a nasal, idrc) cause a voiced onset to nasalise. Now, if the onset is a /j/ or a /g/, the spelling wouldn’t be able to change, since it’s still predictable, and there is no specific way to write a /ɲ/ or /ŋ/ sound. In our case, however, /b/ -> /m/ is very easy to reflect in the orthography simply by swapping out <ba> for <ma>: <na-an-kà-hu-ma-an>
The next sound change is aspirated stops (like the /kh/ in our *nankhuman) turning into homorganic (i.e. same place of articulation) fricatives, so *nankhuman -> *nanxuman -> *nanhuman, however, at this point in time, the original /h/ sound has long since fallen off entirely, so repurposing the syllables <ha>, <hi> and <hu> (now almost always pronounced /a/, /i/ and /u/) for the new /h/ sound is a little contrived, so the spelling will stay the same: <na-an-kà-hu-ma-an>
Now, nasal vowels become long oral vowels before fricatives. However, since there isn’t already a way to mark long vowels, and since nasal vowel characters are the only way to distinguish the consonants /g j/ from /ŋ ɲ/ (as in the word nyāsu, spelt <ya-an-su>) the spelling won’t change. *Nāhuman is still spelt <na-an-kà-hu-ma-an>
The last sound change to take place is shortening/denasalisation of final vowels, which I’ve arbitrarily decided the spelling will lag behind, so once again, the spelling is the same.
The final result in the proper syllabic characters looks like this (reads left to right, no ligatures):
<na-an-kà-hu-ma-an>
/nāhuma/
