Unexplained deletions: continuing what appears to be a common theme
Fragment of a discussion from User talk:Rua
I downloaded a copy of Dolgopolsky's Nostratic Dictionary (https://www.repository.cam.ac.uk/bitstream/1810/196512/49/00ND_ALL.pdf) and searched for "OJ " (note the single space afterwards). Within 13 entries that included a purported Old Japanese cognate, I found the above four errors. I stopped searching at that point; some day I may dig deeper if a further analysis is called for. FWIW, scanning quickly through the next 15 just now suggests a similar error rate.
