A neologism for the governance by grandmothers
I am working on a project about a modern matriarchy. In this political system, the right to vote would be exclusively granted to grandmothers. I am looking to build a neologism that would express this idea.
Neither Gerontocracy nor Gyneco/Gynocracy is correct because this new word must identify specifically grandmothers. Basically I believe that the best would be to find an adequate prefix before the usual ''cracy'' suffix. But I may be wrong.
I found 59 words ending with the Greek suffix ''cracy'' here: http://en.wiktionary.org/wiki/Categor...wordssuffixedwith-cracy
The most popular of these words begin with an ancient Greek prefix. However the word I found for grandmothers in Greek is ''Yaya''. Yayacracy would allow everyone to have a good laugh but I do not think that it would be a good choice.
Another possibility would be to use a Latin prefix. Avia is the Latin for grandmother. It would make Aviacracy. It is my best choice so far. However the prefix ''Avi'' (from the Latin Avis for bird) is also very common as a prefix. So I am afraid that it would bring confusion.
I also found the Italian word Nonna for grandmothers which seems to have roots in Greek and/or Latin. This would make Nonnacracy which may be better than Aviacracy. But here again I am afraid that it would be confused with the prefix Nano or with the negative prefix ''Non'', meaning the absence of power (actually Acracy).
Do you have any advice to help me?
Thank you very much in advance,
