What is the meaning of ぬ in the song ミルクムナリ? (Not the archaic auxiliary verb ぬ)


Call me crazy, but I am trying to translate
[ミルクムナリ](https://www.youtube.com/watch?v=pCflmiwaAXg), which is common played
in Taiko performances, at least in Okinawa; the song is very archaic, as it
speaks of a king from the turn of the 16th century. At the moment, I have been
able to find some interpretative work on some aspects of the song ([lyrics are
available here](https://www.uta-net.com/song/150723/), [an general explanation
of the lyrics is provided here](https://taru.ti-da.net/e759857.html)), but
what I have noticed throughout the song is the use of ぬ, and yet I am unsure
what it is supposed to mean. Here is the first line:

> コドゥシミルクヌ ユガフドゥシサミ

Which means

> 今年弥勒ぬ、豊穣年さみ

I am still trying to determine what さみ is, but the focus for this question is
on ぬ: it is not a conjugation of a verb (弥勒, or みろく in modern spelling, is not
a verb), so immediately most information I have found has not helped. Can
anyone try to provide me some context? It would help since it is used in
almost all parts of the song, as said.




One sense of ぬ in various 琉球語 varieties simply corresponds to の.

While I don't know for sure what さみ is, _if_ we assume it is a copula like だ,
then the sentence would be something like

> 今年弥勒の豊穣年だ

which seems straightforward to interpret.

弥勒{みろく} is a Buddhist deity ([Maitreya
Buddha](https://ja.wikipedia.org/wiki/%E5%BC%A5%E5%8B%92%E8%8F%A9%E8%96%A9)),
or the Buddha of the future to come.

EDIT: [This page](https://taru.ti-da.net/e619390.html) claims that さみ means
〜なのだよ, which would fit perfectly with the above guess.
