[Rounin Ryuuji]

Loss of prenasalisation:

[ʃʒ̩ː.ɣɤ̀ʁ̞]
shih-hèr

'screen; pane of glass; (obsolete) magnifying glass'

[Man in Space]

shih-hèr

I absolutely love the retro Wade-Giles feel of this romanization.

Syllabic fricatives lose syllabicity, causing a true mixed-voice onset to form.

[ʃ͜ʒɣɤ̀ʁ̞]
shih-hèr

'screen, display; (slang) smartphone'

[Rounin Ryuuji]

Epinthesis:
[ʃiʒɣɤ̀ʁ̞]
shij-hèr

'screen, display; (slang) smartphone'

[Travis B.]

Devoice obstruent sequences while lengthening vowels before the former voiced obstruents.

[ʃiːʃxɤ̀ʁ̞]
shij-hèr

'screen, display; (slang) smartphone'

[Rounin Ryuuji]

Postconsonantal [x] > [j].

[ʃiːʃjɤ̀ʁ̞]
shī-shièr

'screen, display; (slang, now dated) smartphone'

[foxcatdog]

Derhotacism with compensatory lengthening and raising.

[ʃiːʃjɯ̀:]
shī-shièr

'screen, display; (slang, now dated) smartphone'

[Rounin Ryuuji]

[ʃ] > [ɕ] before high front vowels and [j]

[ɕiːɕjɯ̀:]
shī-shièr

'screen, display; (slang, now dated) smartphone'

[foxcatdog]

Frankly i don't think this world has smartphones. Now dog companions who fufill the functions of a computer and also connect to the spiritnet is probably what they have.

[Rounin Ryuuji]

Somebody tried to turn a word I contributed for "cardinal" (a species of bird) into the name of a bird goddess (which categorically would not exist in-world), so "mythical creature" to "display screen" seems to be par for the course.

[Travis B.]

[ɕ] > [ʑ] between sonorants.

[ɕiːʑjɯ̀:]
shī-zhièr

'screen, display; (slang, now retro) smartphone'

[Rounin Ryuuji]

Rhotacism, round 2, fricative boogaloo:

[ɕiːʁjɯ̀:]
shī-rhièr

'screen, display; (slang, now retro) smartphone'

[foxcatdog]

*j fortion initially and postconsonantally

[ɕiːʁlɯ̀:]
shī-rhlèr

'screen, display; (slang, now retro) smartphone'

[Travis B.]

[l] > [w] except at the start of syllables.

[ɕiːʁwɯ̀:]
shī-rhuèr

'screen, display; (slang, now retro) smartphone'

[Zju]

Vowel breaking:

[ɕiɐ̯ʁwɯ̀:]
shī-rhuèr

'infodisplay (a kind of future gadget); (obs., archaic) screen, display'

[Rounin Ryuuji]

Continued vowel breaking:

[ɕiɐ̯ʁwɯ̀ɐ̯]
shir-rhuèr

"infodisplay (a kind of future gadget); (obs., archaic) screen, display"

Edit: If everybody's ready to move on, have another one of mine —

蛙杝
kyaradeki
[c͡çʰi̯ɐ̞́.ɾ̪ɐ̞̀.^n̪d̪é̞ˑ.c͡çʰì]
"red maple"

[foxcatdog]

Continued vowel breaking:

[ɕiɐ̯ʁwɯ̀ɐ̯]
shir-rhuèr

"infodisplay (a kind of future gadget); (obs., archaic) screen, display"

Quite a change from...
[kʷɛ̃ŋ.ɣo'cœ́]
kʷɛ̃nɣocœ́
"A nikeeyan guard"

Also
Affricates lenite intervocalically

蛙杝
kyaradeki
[c͡çʰi̯ɐ̞́.ɾ̪ɐ̞̀.^n̪d̪é̞ˑ.çʰì]
"a canadian"

[Travis B.]

Aspirated fricatives don't really exist, so they are being removed.

蛙杝
kyaradeki
[c͡çʰi̯ɐ̞́.ɾ̪ɐ̞̀.^n̪d̪é̞ˑ.çì]
"a canadian"

[foxcatdog]

Taps lost

蛙杝
kyaadeki
[c͡çʰi̯ɐ̞́.ɐ̞̀.^n̪d̪é̞ˑ.çì]
"a canadian"

[Rounin Ryuuji]

Another technically impossible semantic evolution — Canada does not exist in-setting.

Anyway, coalescence of adjacent like vowels

蛙杝
kyādéhi
[c͡çʰi̯ɐ̞̂ː.^n̪d̪é̞ˑ.çì]
"red maple; (world-external) Canada, Canadian"

[foxcatdog]

I was just doing it to mess with you.
