Yes, it was the kwa. I loved the kwa. Anyhow, here are the replacements I've come up with:
kwa > ka Zi ten ka? What do you have?
kyu > ku Ku zi tayar? Are you ready?
The igi 'cause' word is fer, from French faire. The iĝi word, become, is vay, from Frisian, no less.
Go dormvay. I go to sleep. Go tayarfer to komxto. I prepare the food.
Big is now gran, and small is tayn (English tiny) and we shorten them to form gra, a prefix that acts like Eo -eg, and tay, for -et. As modifiers, they mean 'very' and 'slightly/moderately.'
'to go' is now 'gey,' from German, and old ja now means and/or. All four basic connectives are jV.
This isn't all reflected on the Wiki yet. This won't look a whole lot different, but will make parsing things a lot easier.
