Middle Sumri Period Edit

This period covers the changes from Old Sumrë into Middle Sumri up to the 11th Century BR.

Loss of productivity in mobile pitch accent : The mobile pitch accent of Old Sumrë which always had a high pitch on the penultimate syllable (with the exception of definite nouns) was no longer productive in Middle Sumri. While inflected words and compounds formed in Old Sumrë carried their pitch patterns in Middle Sumri, new Middle Sumri compounds didn't follow the pattern of placing the high pitch on the penultimate syllable. OS lústas [lústas] "fruit" → OS lustásvar [lùstásvar] "fruit tree" → MS lustásvar [lùstásvar] "fruit tree" compared to MS lústas [lústas] "fruit" → MS lústaspi [lústaspi] "fruit sack". Notice how the OS compound shifted the high pitch to the penultimate syllable while the MS compound did not. It is from this point on that pitch patterns became fossilised.

: The mobile pitch accent of Old Sumrë which always had a high pitch on the penultimate syllable (with the exception of definite nouns) was no longer productive in Middle Sumri. While inflected words and compounds formed in Old Sumrë carried their pitch patterns in Middle Sumri, new Middle Sumri compounds didn't follow the pattern of placing the high pitch on the penultimate syllable. OS [lústas] "fruit" → OS [lùstásvar] "fruit tree" → MS [lùstásvar] "fruit tree" compared to MS [lústas] "fruit" → MS [lústaspi] "fruit sack". Notice how the OS compound shifted the high pitch to the penultimate syllable while the MS compound did not. It is from this point on that pitch patterns became fossilised. Vowels are dropped between plosives and /l, n, r, s/: OS âtólen [àːtɔ́lɛn] "to turn, to twist, to spin" → MS âtlen [àːtlɛn] "to wind", OS ansóca [ànsɔ́ka] "milk tooth" → MS ànsca [ànska] "milk tooth" Exceptions to this are: when /l, n, r, s. are word final: OS ápal [ápal] "other" → MS ábal [ábal] and not ábl . when before /lC, rC/: OS apáltwo [àpáltwɔ] "to avoid" → MS abáltwo [àbáltwɔ] and not abltwo . when after /Cl, Cn, Cr, Cs/: OS ạglag [áːglag] "trap hunting" → MS ạglag [áːglag] and not ạglg.

OS [àːtɔ́lɛn] "to turn, to twist, to spin" → MS [àːtlɛn] "to wind", OS [ànsɔ́ka] "milk tooth" → MS [ànska] "milk tooth" /wV/ is dropped after plosives and before /s, r, l/: OS upwólen [ùpwɔ́lɛn] "to point, to gesture, to specify" → MS ùplen [ùplɛn] "to single out"

OS [ùpwɔ́lɛn] "to point, to gesture, to specify" → MS [ùplɛn] "to single out" /ɔʊ/ is lost between /n, s/ and /r/: OS atonasówri [atɔnàsɔ́ʊri] "kindness" → MS atnàsri [atnàsri]

Epenthetic /u/ between /m/ and /n/: OS émnen [ɛ́mnɛn] "to be" → MS émunen [ɛ́munɛn]

OS [ɛ́mnɛn] "to be" → MS [ɛ́munɛn] Epenthetic /i/ between /n/ and /m/: OS tínma [tínma] "field" → MS tínima [tínima]

OS [tínma] "field" → MS [tínima] The voiced plosives /b/ and /d/ are dropped intervocalicaly: OS múben [múbɛen] "mountain" → MS múen [múɛn], OS wañídë [wàɲíde] "always" → MS wayí [wàjí]. This change had a great effect on S-nouns whose nominative singular forms ended in /b/ but when inflected the /b/ was intervocalic where it was lost in MS: S-noun: OS tércub [tɛ́rkub] "bone" and tercúbas [tɛ̀rkúbas] "bones" → MS tércub [tɛ́rkub] and tercúas [tɛ̀rkúas].

OS [múbɛen] "mountain" → MS [múɛn], OS [wàɲíde] "always" → MS [wàjí]. This change had a great effect on S-nouns whose nominative singular forms ended in /b/ but when inflected the /b/ was intervocalic where it was lost in MS:

One exception to /b/ being lost intervocalicaly is when it was allophonicaly gemminated in OS, this mosly occurs in non-nominative B-nouns. In this case the consonant became ungemminated: OS estụbab [ɛ̀stʌ́bab] "spider" and OS estụbbë [ɛ̀stʌ́bːe] "spiders" → MS estúab [ɛ̀stúab] "spider" and MS estúbi [ɛ̀stúbi] "spiders".

Consonants voice intervocalicaly: OS áculc [ákulk] "slush" → MS águlc [águlc], OS asrápi [àsrápi] "apple" → MS asrábi [àsrábi]. This has the effect of causing words ending in voiceless consonants followed by vowels to voice when inflected: OS árbat [árbat] "jacket" and OS arbátë [àrbáte] "jackets" → MS árbat [árbat] "jacket" and MS arbádi [àrbádi] "jackets".

OS [ákulk] "slush" → MS [águlc], OS [àsrápi] "apple" → MS [àsrábi]. This has the effect of causing words ending in voiceless consonants followed by vowels to voice when inflected: OS [árbat] "jacket" and OS [àrbáte] "jackets" → MS [árbat] "jacket" and MS [àrbádi] "jackets". /e/ merges with /i/ unconditionaly: OS tër [tér] "sad" → MS tir [tír].

OS [tér] "sad" → MS [tír]. /ɲ/ merges with /j/ unconditionaly: OS ñóca [ɲɔ́ka] "forest" → MS yóga [jɔ́ga].

OS [ɲɔ́ka] "forest" → MS [jɔ́ga]. /n/ becomes /j/ when after /ɛr/ and before a vowel with a medial stage of /ɲ/: OS érnûr [ɛ́rnʌr] "father" → MS [ɛ́rɲʌr] → MS éryur [ɛ́rjur].

OS [ɛ́rnʌr] "father" → MS [ɛ́rɲʌr] → MS [ɛ́rjur]. /g/ devoices word intially: OS gíren [gírɛn] "to fight" → MS círen [círɛn]

OS [gírɛn] "to fight" → MS [círɛn] /h/ is lost unconditionally: OS họyi [hóji] "whisper" → MS ọyi. [ç] becomes phonemic: In OS word final /h/ was realised as [ç]. The loss of [h] caused [ç] to become a phoneme in MS: OS colh /kɔ́lh/ [kɔ́lç] "claw" → MS colh /kɔ́lç/.

OS [hóji] "whisper" → MS /aːwa/ becomes /a/: OS mâwátar [màːwátar] "buzzard" → MS mádar [mádar]

OS [màːwátar] "buzzard" → MS [mádar] /ʌ/ merges with /u/ unconditionally: OS mụlmen [mʌ́lmɛn] "to hunt" → MS múlmen [múlmɛn]

OS [mʌ́lmɛn] "to hunt" → MS [múlmɛn] The sequence /F1VF1/ becomes /F1/: OS ansísten [ànsístɛn] "to whiten" → MS ànsten [ànstɛn]

Malelweri Period Edit

This period covers the changes from Middle Sumri to Malelweri up until the 5th Century BR.

/d/ becomes /d͡ʒ/ : MS àldo [àldɔ] "firewood" → Mw àljo [àld͡ʒɔ] An exception to this is when /d/ is followed by /r, l, w/ : MS àldra [àldra] "torch" → Mw àldra [àldra] "candle"

: MS [àldɔ] "firewood" → Mw [àld͡ʒɔ] The cluster /sk/ becomes /ʃ/: MS scémen [skɛ́mɛn] "to hit" → Mw ṡémhe [ʃɛ́ṽɛ]

MS [skɛ́mɛn] "to hit" → Mw [ʃɛ́ṽɛ] Epenthetic /a/ between /m/ and /g/: MS nímga [nímga] "daughter" → Mw nímaga [nímaga] → nímagha [nímaɣa].

MS [nímga] "daughter" → Mw [nímaga] → [nímaɣa]. Consonantal Apocope: MS árbat [árbat] "jacket" → Mw árba [árba] "jacket" When a word ended in a sonorant followed by a consonant an epenthetic schwa was placed between the two consonants: MS erd [ɛ́rd] "high" → Mw [ɛ́rəd]. The word final consonant was then dropped (ɛ́rəd → ɛ́rə) and the schwa become /ɔ/: Mw éro [ɛ́rɔ] "high". This change had a large effect in merging the buzzard and deer genders. Since the only distinction between the buzzard and deer genders was that buzzard nouns ended in consonants and that deer nouns ended in vowels this change causes every noun to end in a vowel, in effect wiping out the buzzard gender. Some trace of the buzzard gender noun existed in Malelweri as the deleted word final consonants in buzzard nouns were retained when inflected as they were no longer word final. This was quickly leveled out however so that the vast majority of nouns inflected just like deer nouns without the deleted consonant reappearing. Some commonly used nouns preserved the lost consonant. This retention formed a new, but small irregular declension of deer nouns named the buzzard-declension: MS ron [rɔ́n] "dog" and rónu [rɔ́nu] "dog.acc" → Mw ro [rɔ́] "dog" and rónu [rɔ́nu] "dog.acc". However Middle Sumri buzzard nouns that ended in /r/ levelled in Malelweri to join the R-noun declension. Middle Sumri R-nouns ended in /s f, t, d/ but alternated those consonants to /r/ when inflected. In Malelweri the final /s, f, t, d/ were dropped but the /r/ still appeared in inflected forms. As previosuly common declension Malelweri nouns that ended in /r/ dropped the final /r/ but retained in inflected forms showed a similar pattern of retaining the /r/, they were moved to the R-noun declension and adopted R-noun case endings (which were identical to Malelweri common noun endings except that R-nouns has no distinguishable non-nominative plural forms): MS éryur [ɛ́rjur] "father", eryúri [ɛ̀rjúri] "fathers" and eryúran [ɛ̀rjúran] "of fathers" → Mw éryu [ɛ́rju] "father", eryụri [ɛ̀rjýri] and eryụra [ɛ̀rjýa] "father's, of fathers"

MS [árbat] "jacket" → Mw [árba] "jacket"

/z/ devoices to /s/ : MS aslázo [aslázɔ] "orb" → Mw asláso [aslásɔ]

: MS [aslázɔ] "orb" → Mw [aslásɔ] Consonant clusters assimilate in voicing with the first consonant: MS azilcía [azilkíá] "illness" → Mw asilgía [asilgía]

MS [azilkíá] "illness" → Mw [asilgía] The cluster /tst/ becomes /st/ : MS abàltsten [abàltstɛn] "to seperate" → Mw abhàlste [aβàlstɛ] "to split, to crack, to flee"

: MS [abàltstɛn] "to seperate" → Mw [aβàlstɛ] "to split, to crack, to flee" i-umlaut: The back vowels /ɔ, o, u/ front to /œ, ø, y/ when /i/ occurs in the following syllable : MS rúgis [rúgis] "sheath" → Mw rụghi [rýɣi] The front unrounded vowels /{a, aː} ɛ/ round to /ɶ, œ/ when /i/ occurs in the followning syllable: MS atn à sri [atnàsri] "kindness" → Mw atnȁsri [atnɶ̀sri] "joy", MS loréli "stream" → Mw lorẹli [lɔ̀rœ́li] The biggest affect of this was final vowels of nouns mutating due to the common plural suffix being -i /i/. Mw ā̀dbo [àːbɔ] "nightmare" → ȁdbi [ɶ̀dbi] "nightmares"

/p, b, t, k, g, m/ lenite into /ɸ, β, θ, x, ɣ, ṽ/ intervocalicaly: MS asrábi [àsrábi] "apple" → Mw asrạbhi [àsrɶ́βi]. Due to the previous change of V1FV1→FV1 in Middle Sumri causing penultimate /i/ to drop in plural forms of nouns ending in /iC/, when that C was /p, b, k, g, m/ it was no longer in an intervocalic environment when plural, but was when singular. This caused the creation of a new declension named the Si-plurals. MS rúgis [rúgis] "sheath" and rugízi [rùgízi] "sheaths" → Mw rụgi [rýgis] and rȕgzi [rýgsi] → rụghi [rýɣi] "sheath" and rȕgsi [rỳgsi] "sheaths".

MS [àsrábi] "apple" → Mw [àsrɶ́βi]. Loss of /w, r, l/ after a plosive and before a vowel: MS abáltwo [àbáltwɔ] "to avoid" → abhálto [àβáltɔ]

MS [àbáltwɔ] "to avoid" → [àβáltɔ] Metaphesis of /bd/ to /db/: MS ârbdwo [àːrbdwɔ] "nightmare" → Mw ā̀dbo [àːdbɔ]

MS [àːrbdwɔ] "nightmare" → Mw [àːdbɔ] Loss of /r/ before /d/: This change was very restricted and attested only in a handfull of words. MS ârbdwo [àːrbdwɔ] "horror, terror" → Mw ā̀rdbo [àːrdbwɔ] → ā̀dbo [àːdbwɔ]

Maifri Period Edit

This period covers the changes from Malelweri to Maifri up until the 1st Century MA.

Loss of /l/ before vowels : Mw ā́gla [áːgla] "trap hunting" → Mf áiga [áiga]

: Mw [áːgla] "trap hunting" → Mf [áiga] Loss of /j/ and /p/ unconditionally: Mw piyúro [pìjúrɔ] "moon" → Mf iúra [ìúra]

Mw [pìjúrɔ] "moon" → Mf [ìúra] /w/ becomes /f/: Mw äsílawu [ɶ̀sílawu] "morning" → Mf äsíafu [ɶ̀síafu]

Mw [ɶ̀sílawu] "morning" → Mf [ɶ̀síafu] /ɔ, o/ becomes /a/ word finally: Mw äbírdo [ɶ̀bírdɔ] "void, hollow" → Mf äbírda [ɶ̀bírda] "cave" This caused the dative singular case of common nouns to resemble the genitive singular: Mw àncha [ànxa] "storm.gen" and ànchō [ànxo] "storm.dat" → Mf àncha [ànxa] "storm.gen" and àncha [ànxa] "storm.dat"

Mw [ɶ̀bírdɔ] "void, hollow" → Mf [ɶ̀bírda] "cave" /ɛ/ and /ɛi/ merge with /i/ unconditionally: Mw àtne [àtnɛ́] "to give" → Mf áni [áni]

Mw [àtnɛ́] "to give" → Mf [áni] The diphthong /au/ monophongises into /o/: Mw áyu [áju] "smug person" → Mf áu [áu] → ō [óː]

Mw [áju] "smug person" → Mf [áu] → ō [óː] /aː, ia/ become the diphthong /ai/: Mw ā̀ta [àːta] "jewelry" → Mf àita [àita]

Mw [àːta] "jewelry" → Mf [àita] The affricate /d͡ʒ/ goes through a chain shift of /d͡ʒ→j→ʝ→ʃ→x/: Mw mája [mád͡ʒa] "buzzard" → Mf mácha [máxa] The final shift in the chain caused all occurances of /ʃ/ to become /x/: Mw ànṡu [ànʃu] "storm" → Mf ànchu [ànxu]

Mw [mád͡ʒa] "buzzard" → Mf [máxa] Tone affection: /d/ is lost after a vowel and before a consonant followed by a vowel, causing the first vowel to have a low tone and the second vowel has a high tone: Mw ā̀dba [àːdba] "nightmare" → Mf aibó [àibɔ́]. This had an effect of initial mutation of nouns beginning in /dCV/ when following proclitics ending in vowels such as the definite article i [i]: Mf dnó [dnɔ́] "club, hammer" → i nó [ìnɔ́] "the club". /t/ is lost after a vowel and before a consonant, causing the vowel to take a high tone: Mw àtne [àtnɛ] " to give" → Mf áni [áni].

Fricative vowel colouring: Maifri dropped /β, ɣ/ between certain vowels not but before they coloured their surrounding vowels. /aβ{a, o, u}/ became the diphthong /au/: Mw abhálto [àβáltɔ] "to avoid" → Mf áulta [áulta] "to take heed" /Eβ{a, o, u}/ became /juː/: Mw ibhṓju [ìβód͡ʒu] "frog" → Mf yū́chu [júːxu] /yɣi/ became /yi/: Mw artụghi [àrtyɣi] "lightning bolts" → Mf artụi [àrtýi] /œɣi/ became /ø/: Mw sẹghi [sœ́ɣi] "whales" → MF s ọ [sø] /ɶɣi/ became /œ/: Mw uthäghíja [uθɶ̀ɣíd͡ʒa] "leather" → Mf uhẹcha [uhœ́xa] /øɣi/ became /y/: Mw pọghiro [pǿɣira] "toe" → Mf ýra [ýra] /ɔɣV/ became /o/: Mw ārdbógha [à:rdbɔ́ɣa] "misfortune" → Mf airbṓ [àirbó] "curse" /Vɣ{a, ɔ}/ became /uɔ/: Mw aghàpste [aɣàpstɛ] "to dye green" → Mf uòsti [uɔ̀sti] "to change colour" /Vɣ{o, ø}/ became /uo/: Mw púghōje [púɣod͡ʒɛ] "slither" → Mf úochi [úoxi] /Vɣu/ became /u:/: Mw aghúlu [àɣúlu] "garden" → Mf ū́ [úː] /Vɣi/ became /ui/: Mw ā́ghe [áːɣɛ] "to hate" → Mf úi [úi]

Maifri dropped /β, ɣ/ between certain vowels not but before they coloured their surrounding vowels. Elsewhere the fricatives /ɸ, β, θ, ṽ/ become /f, v, h, vn/: Mw änsimhóna [ɶnsìṽɔ́na] "winter" → Mf änsivnóna [ɶnsìvnɔ́na]

[ɶnsìṽɔ́na] "winter" → Mf [ɶnsìvnɔ́na] The diphthong /ɔʊ/ monothongises into /u/: Mw ansówri [ànsɔ́ʊri] → Mf ansúri [ànsúri] "ease"

Pwr Period Edit

This period covers the changes between Maifri and Pwr up until the 7th Centry MA

/k/ becomes /p/ unconditionaly: Mf älchícu [ɶ̀lxíku] "bend, dent" → Pwr olchíp [ɔlxíp] "tear, dent, rip"

Mf [ɶ̀lxíku] "bend, dent" → Pwr [ɔlxíp] "tear, dent, rip" /g/ becomes /x/ unconditionaly: äriúmga [ɶrìúmga] "funeral pole" → Pwr orẃmcha [ɔrúmxa]

[ɶrìúmga] "funeral pole" → Pwr [ɔrúmxa] /u/ becomes /w/ and then /gw/ word initially: Mf uòsti [uɔ̀sti] "to change colour" → Pwr gŵost [gwɔst] If initial /u/ is followed by a consonant then it remains /u/.

Mf [uɔ̀sti] "to change colour" → Pwr [gwɔst] /b/ and /m/ lenite to /f/ intervocalicaly: Mf ába [ába] "evil" → Pwr éfa [éfa]

Mf [ába] "evil" → Pwr [éfa] /g/ is lost after /u/: This change mostly affects nouns with initial /g/ caused by the u→gw/#_ change. When following the proclitic w [u] "deer accusative definite article" word initial /g/ is dropped: Pwr gŵop [gwɔp] "reed bank" → Pwr w ŵop [uwɔp] "the reed bank.acc"

This change mostly affects nouns with initial /g/ caused by the u→gw/#_ change. When following the proclitic [u] "deer accusative definite article" word initial /g/ is dropped: Pwr [gwɔp] "reed bank" → Pwr [uwɔp] "the reed bank.acc" The sequence /aɔ/ merge into /o/, with /o/ adopting the tone that once fell on /ɔ/: Mf aósfa [àɔ́sfa] "coast, shore" → Pwr ọsfa [ósfa]

Mf [àɔ́sfa] "coast, shore" → Pwr [ósfa] /ui/ and /iu/ become /u/: Mf äriúmga [ɶrìúmga] "funeral pole" → Pwr orẃmcha [ɔrúmxa]

Mf [ɶrìúmga] "funeral pole" → Pwr [ɔrúmxa] /h/ is lost unconditionaly: Mf uhẹcha [uhœ́xa] "leather" → Pwr gŵọcha [gwóxa]

Mf [uhœ́xa] "leather" → Pwr [gwóxa] /v/ devoices to /f/: Mf aróva [àrɔ́va] "canopy" → Pwr erófa [èrɔ́fa]

Mf [àrɔ́va] "canopy" → Pwr [èrɔ́fa] /a/ becomes /e/ when word initial: Mf arfói [àrfɔ́i] "to sieze" → Pwr erfó [erfɔ́]

Mf [àrfɔ́i] "to sieze" → Pwr [erfɔ́] /s/ is lost intervocalicaly: Mf isólga [ìsɔ́lga] "lip, show of affection" → Pwr iólcha [iɔ́lxa] "hug" Sporadicaly to prevent a vowel hiatus /ð/ was placed between two vowels that were placed in hiatus after the loss of intervocalic /s/: Mf ạsi [ɶ́si] "sun" → Pwr ódd [ɔ́ð] (the final /i/ was lost in this word due to a later change)

Mf [ìsɔ́lga] "lip, show of affection" → Pwr [iɔ́lxa] "hug" The alveolar plosives /t/ and /d/ become /ð/ before a vowel: Mf àita [àita] "sling" → Pwr aidda [aiða] "sling"

Mf [àita] "sling" → Pwr [aiða] "sling" The front rounded vowels /ø, œ, ɶ/ back to /u, o, ɔ/: Mf sọ /sǿ/ "whales" → Pwr sw [sú] Mf uhẹcha [uhœ́xa] "leather" → Pwr gŵọcha [gwóxa] Mf ạsi [ɶ́si] "sun" → Pwr ódd [ɔ́ð]

Loss of word final /i/ and /u/: The vowels /i, u/ are lost word finally by analogy of the nominative plural ending being /i/ and the accusative being /u/. This analogical originally began in nouns to avoid ambiguity but soon spread to other words and became a sound change. Due to the origin of this change the nominative plural and accusative endings were left intact : Mf ạlchi [ɶ́lxi] "flame" → Pwr olch [ɔlx], Mf ävisacu [ɶ̀vísaku] "best friend" → Pwr ofíap [ɔfíap]

The vowels /i, u/ are lost word finally by analogy of the nominative plural ending being /i/ and the accusative being /u/. This analogical originally began in nouns to avoid ambiguity but soon spread to other words and became a sound change. Due to the origin of this change the nominative plural and accusative endings were left intact : Mf [ɶ́lxi] "flame" → Pwr [ɔlx], Mf [ɶ̀vísaku] "best friend" → Pwr [ɔfíap] [ð] devoices allophonicaly to [θ] after /s/: Pwr eddàsdd [ɛðàsð] "to polish" → Pwr eddàsdd [ɛðàsθ]

Pwr [ɛðàsð] "to polish" → Pwr [ɛðàsθ] Loss of low pitch
