Thanks, I'll chek this thred out. :-)

Possibly, but it still seems a little contrived. Maybe if an /N/ were

Now that's something I haven't heard of, and maybe I could link Yasaro 
to some older Zireen languages (like Tenai) which have ejective stops 
(one of the sources of tones in Simîk). Or ejectives / glottalization 
could be an areal feature of otherwise unrelated languages, which would 
simplify things.

/ti/ is at least as common in Yasaro as /ki/ if not more so; /tj/ /kj/ 
and so on are possibilities, but if these existed in the older 
languages, other clusters probably existed as well. Unless /j/ came from 
/i/, but then /ji/ seems problematic.

I was thinking of Latin plorare > Portuguese chorar, /pl/ > /S/, which 
is pretty close to /pl/ > /tS/ and could possibly be adapted. But most 
likely /tr/ or /kr/, especially since /r/ is really [z`] in Yasaro. /tK/ 
is another interesting possibility, since /K/ is frequent in Zireen 
languages but absent in Yasaro.

I'm running out of places to relocate stress. A word like /su:_Fri/ 
"hammered dulcimer" would originally have been stressed on the first 
syllable, /'su:ri/, while /sa_Rva/ "white" would have been stressed on 
the second syllable, /sa'va/.
