Month names collection / metastudy

[Koen G]

Many interesting findings! Some points:

* In case of doubt, I'd opt for "abriil" over "abrül". At first glance, it looks like the form in "Abriil" is rounder than "ü" elsewhere, which is quite spiky at the bottom. But it's hard to say. Since we're not sure, I'd say "abriil" with its two minims is more neutral. But both are really okay, this has no impact on the scoring system or anything.

* Of the -ris/ri endings, as you probably expect, these are inflected Latin forms again, genitive this time.

* I do not think the VM septēb' can be "septembris", since there is no reason to use a Latin genitive here. The 9 other month names are nominative. I personally don't think we should assume that it develops to anything other than "septembre". Any argument based on another form would be extremely speculative, given the full sequence.

* The most interesting thing is indeed the occurrence of "octembri" here, (which would presumably be "octember" in the nominative). This may be a clean case of what was described in this older source we discussed before: authors writing in the vernacular equalizing the Latin sequence.
