Re: Sound change rules for erosion

Well, if I wanted depth, I think I'm well on my way.  Next up after this
will be mangling vowels till I have about twelve of them.

Here is the first part of a short myth I wrote to put the language through
its paces, in proto-speak followed by stage-1 sound-change:

the-moon his-mother she-is-her the-sun.  I-tell-about-it how it-happened
she-got-pregnant.

li-ruhaku kato-wimituwo kito-lelasa li-luworu.  we-lerirelo wihu me-halipo
me-lipehawike.

líruakú kátoPmítum kítollása lílumrú.  wélerrélo wíhu méhalpó mélifháwix.

Nouns are preceded by either a determiner or a possessive.  The determiners
are: li, for unique, known or named things; ma, for indefinite things which
have not been mentioned yet; and ka, for referring to items already mentioned
in the conversation.

Possessives are several:

wole    pref. their
sara    pref. your pl.
hetu    pref. our excl.
lusa    pref. our incl.
lawe    pref. its
kato    pref. his
mowi    pref. her
pewi    pref. your
siku    pref. my

Since the possessives are two syllables and the determiners one, and the
accent is always on the first syllable with syllables divisible by three
losing a vowel (or occasionally a consonant), the possessed and non-possessed
forms of nouns are going to look very different.  I forsee dictionaries
(when they get around to them) having to cite every noun in one determiner
form and one possessed form.

Here are some examples:

mapamawape --> mápamwápe                A woman
kapamawape --> kápamwápe                The woman
lipamawape --> lípamwápe                Woman
sikupamawape --> síkupmáwaf     My woman
pewipamawape --> péwipmáwaf     Your woman
mowipamawape --> mówipmáwaf     Her woman
katopamawape --> kátopmáwaf     His woman
makowapo --> mákowpó    A child
kakowapo --> kákowpó    The child
likowapo --> líkowpó    Child
sikukowapo --> síkugwápo        My child
pewikowapo --> péwigwápo        Your child
mowikowapo --> mówigwápo        Her child
katokowapo --> kátogwápo        His child
mawimituwo --> máwiwtúwo        A mother
kawimituwo --> káwiwtúwo        The mother
liwimituwo --> líwiwtúwo        Mother
sikuwimituwo --> síkuPmítum     My mother
pewiwimituwo --> péwiPmítum     Your mother
mowiwimituwo --> mówiPmítum     Her mother
katowimituwo --> kátoPmítum     His mother

And I don't have time to get into the verbs, which are really fun.

Of note is the fact that any noun or verb root, regardless of the number
of prefixes attached to it, will show up in one of three forms corresponding
to which of the three phases of the stress pattern the root ends up starting
on: the stressed syllable, the unstressed syllable, or the dropped-vowel
syllable.

Here are the current sound change rules, in the Sound Change Applier's
(admittedly limited) format:

C=ptkmlrswhfTxSbdgzLP
T=ptks
F=fTxS
D=bdgz
M=wm
W=Pw
*P is wh
N=lw
L=Lm
*L means dark l
H=h
V=aeiuo
A=áéíúó
I=ei
U=ou
* Set up dactylic rhythm
+V/+A/#+C_
+V/+A/+A+C+V+C+V+C_
+V/+A/+A+C+V+C+V+C_
+V/+A/+A+C+V+C+V+C_
+V/+A/+A+C+V+C+V+C_
* Vowels who are about to die do things to consonants
+T/+F/+A+C+V_+I
+T/+D/+A+C+V_+U
+H//+A+C+V_+V
+M/+W/+A+C+V_+I
+N/+L/+A+C+V_+U
* Bye-bye vowels!
+V//+A+C+V+C_
