The story
Coined circa 1975–1980 by Professor Jürgen Spranger of Mainz, West Germany, in the usual scientific tradition of ISV terms based on New Latin and Ancient Greek. The osteo- prefix was added to a transliterated and mutated form of γλυφίς (gluphís), and the adjective ends in the suffix -ic. Greenberg and Lewis (1990) pointed out that the -glo- syllable would have been better transliterated as -gly- and that the following syllable should have been different as well. Regardless, though, the word osteoglophonic is firmly established as a fait accompli.
