Idoburgish/Sound Changes

Bleh.

The sound changes
No specific order, though. I am a noob at putting the sound changes in an order, therefore I request the order of sound changes not to be a reason to give lesser preference to Idoburgish.

Here P = plosive, O = obstruent, J = /n t d s k g x/ (Consonants which may be palatalized. There's a shitload of fuss over them, so they'll be explained later.) -Umlaut- The umlaut is greatly reduced, with only the i-umlaut left in widespread use. a e > e i /_$i ! {a: o:} ai ei > ei ii /_$i (stadiz > stediz ! ailidaz > ailidaz) - Stage 1 - z > 0 /_# (ailidaz, niftiz > ailida, nifti) z > r (betizô > betirô) awj > aij (awjō > aijō) wj > j: /V_V (niwja > nij:a) wj > j (if exists) ai > e: (ailida > e:lida) au > u: (kaupo:na > ku:po:na) h > 0 /_C ! /V_C (hrinþa > rinþa ! tahrą > tahrą) ą > 0 /_# (je:rą > je:r) ō ô ǭ > a /_# (e:jō > e:ja) þ > d (þurp > durp) VC:a > V:Cə (nij:a > ni:jə > !ni:wə) s > 0 /C_# (e:ks > e:k) a > ə /_# (rinda, e:ja > rində, e:jə) ǫ̂ > (an >) ən /_# (wulfǫ̂ > wulfən) ə > ʲ /J_# (rində > rindʲ) i > ʲ /J_C l_C (e:lidʲ > e:lʲdʲ) ə > i /_# ! /j_# (betʲrə > betʲri; ni:wə > ni:wi ! e:jə > e:jə) i > ʲ /_# (nifti > niftʲ) si > ʃ /_# (hesi > heʃ) tj > tsʲ /_V (matjan > matsʲan) g > j /#_V (gaskaftʲ > jaskaftʲ) ja jo > je (jaskaftʲ > jeskaftʲ) Jji Jjə > Jʲ /C_# (nidjə > nidʲ) ji jə > j /_# (e:jə > e:j) j > xʲ? /V_# ! /i_# (e:j > e:xʲ) P[+voiced] > P[-voiced] /_# (rinʲdʲ, elʲdʲ > rinʲtʲ, elʲtʲ) << only in speech C1C2ʲ C1ʲC2 > C1ʲC2ʲ (rindʲ > rinʲdʲ) << SAP Cʲ > C /_C (betʲri > betri; e:lʲd > e:ld) << only in writing P[+voiced] P[-voiced] > P[-voiced] P[+voiced] /#_V (durp > turp) sk > ʃ /_V[+front] (skind > ʃind) sC > ʃC (stetʲ > ʃtetʲ) - Stage 2 - Umlaut: o u > ö /_$i ! oi ui > öi eu > ö (sceutan > scötan) oi > ö (ējōi > ējo /e:jø/) iu wi (> y) > ø ! /#_ (swimsl > sömsl) jV[+front] wV[+back] > V: (jitsj > ītsj; wundr > ūndr) j > 0 /#_V[+front] (jescötj > escötj) w > 0 /#_V[+back] è > ə (e'ʃøc > ə'ʃøc) << only in speech ə > e /Cj_ (farjən > farjen) << SAP PF > FP /_# (ītsj > īstj /i:ʃc/) p > ff /V_V (sēpe > sēffe) V: > V /_C1C1 _$[+long] (sēffe > seffe) t tj d dj > 0 /O_# (lehdj /leçc/ > lech; īstj > !īstj) {t d} {tj dj} > p i /m_# (gemtj > gemp; !gemdj > gemi) {t d} {tj dj} > k hj /n_# (gind > gink) hj > h(h)i /_# (ēch > ēh(h)i /e:çi/) << the  here counts as long in sound changes and this has a lot of irregularities Cl > Cle /_# (sömsl > sömsle) s > sc /_V[+front]V _ø (sömsle > scömsle) ų > e [ə] /_# (eekų > eeke) u > i /N_# (ginnu > ginni) u[-stressed] > e /C_N# {u e i}[-stressed] > 0 /C_CV C_C# u[-stressed] > 0 /C_# ! /Cn_# (wintru > wintr) Vn V:n > Ṽ /_C _# ! /#_# ən > ə̃ (wrecan > wrecą; warōn > warǫ; tagān > tagą; farjen > farję ! in > in; ūlfen > ūlfen) << distinguished in writing only partially {je ja} {ję ją} [+unstressed] > i į (farję > farį) tr dr > tsj /_C _# (ųdr > ųtsj) d > j /V_#[+front] ! /V_#[+front, nasal] (pirid > pirij) Vj[+front] Vw[+back] > V: (pirij > pirī) V > V: /_hCC _hC# (tahr > tāhr) hC > C /_C _# (tāhr > tār) << and previous are messing things up:  in nom. but in dat.

There are s**tloads of both.

Orthography: Stage 2: <-j> for palatalization;  for /ʃ/ before front vowels and /sk/ elsewhere;  for /ʃ/; macrons for long vowels;  for /x/ and /ç/ before  ;  for /ç/ elsewhere; <ö> for /ø/ except after , where /ø/ is denoted by ;  for /k/ everywhere.

Stage 3 (modern):  for all /ʃ/,  for /k/ everywhere, <ö> for all /ø/;  for hard /g/ and word-final /g/ after /n/. Irregular tonality: acute and grave accents for rising and falling tones respectively.
