So, while I sit here with a plumber working on my shower, I finally pulled the trigger on a change I've been thinking about for a while for Kahtsaai. One of the slot-one prefixes for verbs is -na'a- which marks distributed or widespread activity. Thinking about common uses for a while, I decided it needed to merge with two of the person prefixes for subject, he- (3 inanimate) and hááí- (3pl. animate).
The resulting portmanteaus are he'a- and háá'ya-, giving such fun as he'a'ánméín It's going to be hot (everywhere) (I hear), and háá'yawósénats they were running around everywhere.
That change only took a week to commit to.
