Easy ones first:
Xazengri - *Xa-zen-ri
Bolongri - *Bo-lon-ri
Corauši - *Tu-ral-šin; the only one to use -šin rather than -ri - is there a variant *Coralauri or similar to emphasise the peculiarities of Coralaur speech rather than the standard language, or is the standard still close enough that there's no meaningful distinction?
Evangri - *E-van-ri; not from Lake Van, but from the name of the god associated with it; the two are understandably somewhat difficult to untangle.
Jimbri - *Jil-me-ri
Idestri - *Ye-de-veiz-ri; that's one hell of a phonetic reduction.
These I'm not completely sure of:
Rajjari - *Ran-ja-vi-ri or *Ran-ja-ri depending on whether the word has been regularised in modern Xurnese.
Lejur - *Lij-u-ri; I couldn't find an Axunašin etymon, which doesn't help,
And the two I can't do:
Momori - couldn't find an Ax. etymon, no Almeopedia page for Momor.
Čimagri - clearly from Čimaq + -ri, but again, no Ax. etymon or Almeopedia page.
