Month names collection / metastudy

[Zauriek]

In german, for sure. But in french? The spellings (for the month names at least) are remarkably consistent across hundreds of manuscripts.

Maybe that is why old german borrowed terminology from the french and latin, they were trying to solidify a standard for month names and then they tried to make their own dutch-like nomenclature by making weird mixes, and with the gradual pass of time, the references were slowly solidifying due popularity referencing until the standard month names in dutch were made or maybe this is bonkers and the final dutch names for months were impossed by a king or something like @R. Sale said. 

Iollet feels like an intentionally twisted french word, like they borrowed juing and decided to declare war on it. Wait, could juing had another meaning in old german, so it could not be used? i don't know, maybe that is why they changed some of the month names, no idea really.

Aberil feels like aberellen + aprilis mix combo: [aberellen + aprilis | aberel + april | abe-ril] In this context the word was made to reference the two languages used for the month, as if there was some kind of need to write a month in more than 1 language for clarification or something.

[i'm a little bit worried by my lack of knowledge in this, hope it is all good.]
