Snake Phonotactics

In my version of Parseltongue, here are the phonotactics:

(The tap is the alveolar flap and the click is dental.  ugh.)  You can start anywhere.  There is no boundary between words.  Epenthetic 'a's will probably abound.  I need to wrap my head around 's' being the resting sound, like 'uh' in English.

Lexical Intentionality in Fluid-S Alignment

So, I'm imagining a language which uses Nominative (N), Accusative (A), Ergative (E), and Absolutive (B) cases.  The verbs do not inflect for voice, but have a lexically expected case.  For active verbs, this is either N or E.  For stative/descriptive verbs, this is either A or B.   I imagine a good N-verb might be "to eat", an A-verb "to be red", an E-verb "I punch", and a B-verb "to be reddened".  Here goes:

	Case Expected
Case Given	N	A	E	B
N	Normal Intentionality	Average Causality	Unintentionality	Unintentional Causality
A	Passive Voice	Normal Descriptive	Unintentional Passivity	Pseudo-Passive Object
E	Screaming Intentionality	Screaming Causality	Strong Intentionality	Intentional Causality
B	Intentional Passivity	Pseudo-Passive Voice	Anti-passive Voice	Normal Stative

OK, that kinda worked. Let's try it with the verbs I mentioned, imagining an Ergative-Absolutive alignment when needed:

	Case Expected
Case Given	N	A	E	B
N	I ate	I made (it) red	I punched (him) on accident	I was reddened on accident
A	I was eaten	I am red	I was punched (by him) on accident	I got reddened
E	I ate on purpose	I made (it) red on purpose	I punched (him)	I reddened (it)
B	I was eaten in purpose	I got (it) red	I was punched (by him)*	I was reddened

I have no idea if I'm murdering Fluid-S or not. I better ask some people.
