Omaha nasal vowels

[Ardis R Eschenberg]

John,
Wow.
Okay I will need help with the historical reasonings as the only
historical notions I have are from comparing UmoNhoN with the Lakhota I
know (not very in-depth!).
Some examples of oN transcribed as uN before a back consonant are:
iNgdhoNga 'cat' as iNgdthuNga
ichoNga   'mouse' as ichuNga  (the first 'i' may also be nasal, it seems
to vary by speaker a bit)

Please do send me a list of words to elicit on aN vs. oN.  I'd be happy to
check as they come up.  I was doing this last year but inconsistently
which leads to little conclusion.
