Word evolution game

[Rounin Ryuuji]

Language 1: Assibilation, and an orthographic reform:

[six]
zich

Language 1.5: [x] > [ʃ] before front vowels, another orthographic reform:

[ʃix'xai]
Scicchai

Language 2: [eː] > [ia], another orthographic reform

['keːis]
tiais

Language 3: [s] > [ʃ], orthographic form

['ʃyː]
Schüh

[vegfarandi]

A wave of word final voicing whooshes across the land.

Language 1:

[siɣ]
zich

Language 1.5:

[ʃix'xai]
Scicchai

Language 2:

['keːiz]
tiais

Language 3:

['ʃyː]
Schüh

[Travis B.]

Instead of focusing on single words, I'm going to start a new set of words, in this case English one through ten:

one two three four five six seven eight nine ten
[wɐ̃ːn tʰʉː θɻiː fɔːɻ faːɪ̯v sɪʔks ˈsɛːvn̩ eʔt nãːɪ̯̃n tʰɛ̃ːn]

and I am going to split it into two different dialects:

The first will have final devoicing:
[wɐ̃ːn tʰʉː θɻiː fɔːɻ faːɪ̯f sɪʔks ˈsɛːvn̩ eʔt nãːɪ̯̃n tʰɛ̃ːn]

The second will have the NCVS:
[wʌ̃ːn tʰʉː θɻiː fɔːɻ faːɪ̯v sɘʔks ˈsɜːvn̩ eʔt nãːɪ̯̃n tʰɜ̃ːn]

[Rounin Ryuuji]

Language 1: Non-nasal long high vowels diphthongise:
[wɐ̃ːn tʰʉu θɻɪi fɔːɻ faːɪ̯f sɪʔks ˈsɛːvn̩ eʔt nãːɪ̯̃n tʰɛ̃ːn]

Language 2: Loss of terminal nasal consonants after nasal vowels (syllabic nasals remain):
[wʌ̃ː tʰʉː θɻiː fɔːɻ faːɪ̯v sɘʔks ˈsɜːvn̩ eʔt nãːɪ̯̃ tʰɜ̃ː]

[Travis B.]

Language 1: Open diphthongs become monophthongs while close diphthongs open some.
[wɐ̃ːn tʰəːu̯ θɻəːi̯ fɔːɻ faːf sɪʔks ˈsɛːvn̩ eʔt nãːn tʰɛ̃ːn]

Language 2: Initial fricatives voice.
[wʌ̃ː tʰʉː ðɻiː vɔːɻ vaːɪ̯v zɘʔks ˈzɜːvn̩ eʔt nãːɪ̯̃ tʰɜ̃ː]

[Rounin Ryuuji]

Language 1: Glottal stops vocalise to [ɐ], mild spelling reforms influenced by Dutch:
[wɐ̃ːn tʰəːu̯ θɻəːi̯ fɔːɻ faːf sɪɐks ˈsɛːvn̩ eɐt nãːn tʰɛ̃ːn]
wonn, touw, thrie, foar, fyve, six, seven, eight, nyne, tenn

Language 2: Non-Rhotacism, no spelling changes:
[wʌ̃ː tʰʉː ðɻiː vɔːɐ vaːɪ̯v zɘʔks ˈzɜːvn̩ eʔt nãːɪ̯̃ tʰɜ̃ː]
one, two, three, four, five, six, seven, eight, nine, ten

[Darren]

Language 1: Coda nasals lost
[wɐ̃ː tʰəːu̯ θɻəːi̯ fɔːɻ faːf sɪɐks ˈsɛːvn̩ eɐt nãː tʰɛ̃ː]
wonn, touw, thrie, foar, fyve, six, seven, eight, nyne, tenn

Language 2: /tʰ/ → /s/, spelling adjusted
[wʌ̃ː sʉː ðɻiː vɔːɐ vaːɪ̯v zɘʔks ˈzɜːvn̩ eʔt nãːɪ̯̃ sɜ̃ː]
one, swo, three, vour, vive, zix, zeven, eight, nine, sen

[Rounin Ryuuji]

Language 1: Schwas assimilated to following diphthong elements; further slight orthographic changes.
[wɐ̃ː tʰoːu̯ θɻeːi̯ fɔːɻ faːf sɪɐks ˈsɛːvn̩ eɐt nãː tʰɛ̃ː]
wonn, tôw, thrêi, fôr, fâve, siks, sêven, eight, nâne, tenn

Language 2: /ð/ → /z/; Language 1's orthography begins to influence that of Language 2:
[wʌ̃ː sʉː zɻiː vɔːɐ vaːɪ̯v zɘʔks ˈzɜːvn̩ eʔt nãːɪ̯̃ sɜ̃ː]
wonn, sû, zrie, vôr, vâive, zeuks, zevn, eght, nâine, senn

A bunch of proto germanic mammal names. Some of these are hypotheticals and some of these don't really work with their english equivalents. The *a stems come in 3 different varieties for males, females and diminuitives. Germanic has 3 primary branches so i suggest whoever kicks of the sound changes starts with 3 forms.

Frankly i think i jumped the gun on introducing a new topic. This one still has so much potential. Anyways i am incorporating Rounins changes.
