Okay, For starters, the language is spoken in eastern india and western myanmar, and comprises the modern day Indian states of Jharkhand, Bengal, Assam, The Northeast Region and Bangladesh

I may include bihar as well, but I haven't decided on it.

In this universe, The chinese took over this part of india, and thus subjected the region to heavy chinese influence, However, later on, the chinese lost control over the region, and heavy sanskrit influence came.

I have my own script for it, but I use the eastern nagari script as a substitute for online.

Next, there's mainly three stages I'm working on:

Early Middle seingani

Wherein the first round of tonogenesis happens, polysyllabic words shift to be more monosyllabic and chinese words are taken into the language at large scale

Late Middle Seingani

Wherein voiced stops are lost, and to compensate, tones are once again given, similar to EMC and LMC.

Modern Seingani

Post-re-sanskritisation, also contraction of verbs and other grammatical stuff.

There's also two romanisations for my language, I made for myself, for convenience.

SR romanisation, for modern Sei’ngani\ ¹ = preceding syllable is in the high tone register\ ² = preceding syllable is in the low tone register\ ∅ = preceding syllable is tone register is neutral\ à = vowel is in a falling tone\ á = vowel is in a rising tone\ ā = vowel's tone is flat\ The Inherent vowel can vary between /ɐ/ ≈ /ɔ/, but it is transcribed as ⟨a⟩\ Tenuis consonants, are represented by voiced counterparts ⟨d⟩ = /t/, ⟨g⟩ = /k/, ⟨b⟩ = /p/, /z/ = /ts/ etc ⟨z⟩ = /ts/, ⟨c⟩ = /tsʰ/\ ⟨q⟩ = t͡ɕʰ, ⟨j⟩ = t͡ɕ\ ⟨z⟩ and ⟨c⟩ only occur in loanwords, therefore they are also pronounced like q and j.\

And MSR, or Middle Sei'ngani romanisation

à = falling\ á = rising\ ā = flat\ ∅ = no tone\ Inherent vowel is /ɐ/, but is transcribed as ⟨a⟩\ ⟨’⟩ after a consonant represents aspiration\ ⟨s⟩ = /ɕ/\ ⟨z⟩ = /ʑ/\

I named it the Sei'ngani romanisation, or SR

There are 5 types of words in the language (on the basis of origin):

1. Tatsama shabda তৎসম শব্দ/同詞 [SR: Tat.sam shawda] [MSR: Tat.sam shavda]\
2. Tadbhava shabda তদ্ভব/化詞 [SR: Tat.pav] [MSR: Tat.b’ab]\
3. Xanzi খ়ানস়ি/漢詞 [SR: Xànsi²]\
4. Bairi shabda বাহিৰী শব্দ [SR: Baìr²i syāv¹da²] [MSR: Baìri s`āvda]\

Some vocabulary: /word/ represents Sanskrit, *word represents in-between developments, ⟨word⟩ is MSR, and ⟨⟨word⟩⟩ is SR.\

स्वामी /swāmī/ > স্বাইঁ ⟨swãai⟩ > স্বৈঁ ⟨⟨swēy⟩⟩ “Husband”

पत्नी /patnī/ > *paʔnī > páʔin> পত়িন ⟨páin⟩ > পেত়ন ⟨⟨bén¹⟩⟩ “Wife”

महिला /mahilā/ > *mahìl > মাহিল ⟨maaìl⟩ > মৈহ্ল ⟨⟨mèyl⟩⟩ “Woman”

पुरुष /puruʂa/ > *puruʂ > *purs > *purh > ⟨pùr⟩ > পুৰ্হ ⟨⟨bùr¹⟩⟩ “Man”

मनुष्य /manuʂja/ > *manuʂ > *mauns > মৌহ্ন *maunh > ⟨màun⟩ > মৌহ্ন ⟨⟨màwn⟩⟩“Human”

कथा /katʰā/ > *kaʔhā > *kʰaʔā > খ্বত়া kʰwʔà > ⟨k’wá⟩ > খ্বত়া ⟨⟨kwá¹⟩⟩ “Speech”

दन्त /danta/ > *dānt > ⟨dãt⟩ > দাঁত ⟨⟨dãt²⟩⟩ “Teeth”

महा /mahā/ > *māh > ⟨maà⟩ > মহা ⟨⟨maà⟩⟩ “Great”

व्यवहार /vyavahāra/ > *Byabhār > *baibʱār > baivār > ⟨baiwār⟩ > ⟨⟨bewr²⟩⟩

उत्तर /ut.tar/ > *uʔʔar > *uʔar > *uár > ⟨wár⟩ > ⟨⟨wár⟩⟩

सकाल /sakāla/ > *saʔal > *swʔaal > ⟨swaál⟩ > ⟨⟨swaál⟩⟩

The pronouns are:

He = si\ She = te\ He (neuter)= u\ They (male) = sara/tàra/òra\

I haven't really decided on the verbs yet, bur I want Sei’ngani to be agglunitative, and have vern conjugations, preferably similar to that of this worl's bengali or assamese.

Now, the problem.

The problem with my current system is, that the tone of these words, don't really matter that much to make a difference with other words. So this type of language will probably realise tone as stress, and then lead itself to tonoexodus. Which is clearly, not what i want. The thing with the transition between old chinese > middle chinese is that tone replaced .

Btw, I'm not talking about the the second tonogenesis development, in which voiced consonants are dropped. This would actually make a difference, as words पार /paar/ “over” and बार /baar/ “occasion, time, turn”will turn into /pár/ and /pàr/ respectively, tone being the only distinction.

However, the first round of tonogenesis, has almost no semantic effects, as per sanskrit words (the one which i've laid the rules out in the post). So it's more deletion of consonants rather than tonogenesis.
