It's been a while since I did any significant conlanging, so I thought I'd share some of my most recent efforts. Some people may be familiar with Aeruyo, which has a grammar posted on this site. Within the same world that Aeruyo and its speakers, the etherial Aeruro, exist, there are also the Malviz. The Malviz are another group of spiritual beings who split off from the Aeruyo in time immemorial and cover and are essentially the "dark" version of the air spirits.
Malviz speak a decendant of Aeruyo, the conceit being that Aeruyo did not actually change much because its primary speakers are immortal and have separated themselves more from the physical realm, whereas the language of the Malviz has changed slowly but surely due to their constant interaction with the changing world through possession of undead. This may be a very flimsy hand-wave (and may need beefed up in my stories), but it allows me a nice sandbox to play with historical changes before I get serious about working out the human languages of my world.
My process for making the sound changes to Aeruyo to Malviz went somewhat backward. I had a couple of names that I wanted to fit into the ending Malviz language -- namely Kavrz [kʰavʐ]* "Malviz incarnate of wrath" < kafira "anger" and Malviz [malvɪz] < malefiri. After building the sound changes that would result in those two forms, I built out a couple more changes. Here's what I came up with:
- V > 0 / _#
- stress shift to first syllable
- a, e, o, u > ə / [-stress]
- i > ɪ / [-stress]
- [-aspirated] > [+voice] / V_
- j, w > 0 / [-continuant]_
- ɾ > ɻ
- V > 0 / [+stress]._
- ɻ > ʐ / _#
- [+aspirated] > [-aspirated] / ._[-stress]
- w̥ > ɸ
There are no strict time frames here -- again, I am building these languages kind of in a sandbox, taking advantage of the conceit that they are spoken by immortal spirits who reject influence of mortals, etc etc. I may add a few sound canges (I'm looking at diphthongization) or rejigger the order, but so far this seems to be a good start for me. I feel the next step is to use these and run my inflectional paradigms through Zounds and then work out what additional morphology changes follow from that. I already know that I'll be losing the negative verb forms to that very first apocope, so I'll need to make a negative particle -- I plan on using men "never".
*Yes, these are phonetic transcriptions. I will have to work out allophony after I have figured out precisely how the sound changes are affecting everything.
