Month names collection / metastudy

[Koen G]

Lists that get all three wrong are not likely to be helpful at all.

I agree that some minimum requirement is necessary. But if we want at least two of the criteria you outlined, we're still far off. In the current list, only the astrolabe (if it is transcribed correctly) has both "jong" and "octembre". None of them have "b" in "avril". 

I would also say that the option of "yony" must be disregarded. The final letter is "g".
