The isolating language, post #3:

I guess it is time to attempt some kind of phonology - and violate the guiding principle of avoiding phonologies here. Writing this post has felt quite unappealing, as I've just abhorred the idea of having a phonology here. It's necessary though, for the further development of the language. Just think of it as me writing this post so I can write future posts.

Stops:
The main distinctions are

	Bilabial	Lab-dnt	Dental	Alveolar	Palatal	Velar	Uvular	Glottal
Stops	ph p' b		- - ð	th t'	ch c' ɟ	kh k'	qh q
Fricative			ð	s z	ç ʝ	x h	R	x h
Lateral glide				l	λ
Trills and glides	w			r	j		R
Nasal	m			n	ɲ̟	ŋ

Historically, /g/ has become dž in most contexts, and h in some. /x/ and /h/ are only marginally distinct, as are /c/ and /j/. /w/ mostly appears in complementary distribution with /b/. /d/ is now /ð/, and strictly speaking a fricative, but patterns more like a stop. The uvular trill/fricative patterns like both trills and fricatives.

The stops also sometimes appear allophonically as affricates, e.g. syllable-finally after closed vowels or r.

The syllable structure is CCVCC the main restrictions being:

• no two homorganic stops in a sequence except over a syllable boundary
• no uvular and velar stops in a sequence except over a syllable boundary
• the syllable coda has quite a few restrictions on it, unlike the syllable onset

Vowels:

i			u
e	ə
	ɛ		o
			ɑ

In stressed, open syllables, these tend to diphthongize: /i/ tends towards [ij], /u/ towards [uw], /e/ towards [ei], /ə/ towards [eə], /ɛ/ towards [ɛa], /o/ towards [oi] and /ɑ/ towards [ou].

Basically, an isolating language is boring in the way that you do not get any morphophonology to work with. One can still create some interesting things over word boundaries - certain sounds get deleted in the presence or absence of other sounds, mutations, assimilation, etc. I think stress shifts might also be caused by stressed syllables getting too close. So that should basically provide sufficient pseudomorphophonology for there to be some interesting stuff.
