Future Poswa

Future Poswa is a hypothetical projection of the Poswa language about 4000 years into the future, after its speakers had been overwhelmed by immigration from the Moonshine Empire. (I have also worked out sound changes for Future Moonshine, but Moonshine does not have enough vocabulary or grammar worked out yet for me to make any meaningful sentences in it.)

Sound changes

Future Poswa will change very slowly, as the conservatism that characterized Poswa for its entire history as an independent language remained firm even with the pressure of the Moonshine-speaking overclass. On the other hand, the Poswobs adopted many words from Moonshine.

Labialized consonants are retained, but there is no longer a perfectly symmetrical setup with one labialized consonant for each plain consonant. Instead, all^? labialized consonants simply become rounded bilabials, such that, for example, Poswa swi "I slept" becomes Future Poswa fʷi.
