Meta: Morrigan, Morrighan'nan, and Flemeth (and some elven linguistics)

(This post was originally posted on Reddit. I edited out about four words regarding Tyrdda's ancestry.)

What is the connection between Morrigan and Morrighan'nan?

The Avvar mage Tyrdda's legend speaks of a mysterious Lady of the Skies who just happens to sound a lot like Flemeth. This Lady of the Skies nudges Tyrdda to get pregnant so she'd eventually have a descendant named Morrighan'nan, a female Avvar chieftain of great power.

There's not much else known about how they're connected to Morrigan but something that struck me was Morrighan'nan's name. Now, it's easy to be distracted by the Morrighan part at first glance but what stood out to me was the ending, 'nan. It reminded me of Elgar'nan, the Evanuris/elven god of vengeance whose name can be broken down as:

elgar = spirit

nan = revenge, vengeance, violent rage, especially violent rage in purpose of revenge

Thus Elgar'nan essentially means Spirit of Vengeance.

Could Morrighan'nan also be an elven name? She wasn't an elf but that doesn't mean elves couldn't refer to her by a different name (see Flemeth vs Asha'bellanar). Breaking down her name gives us:

mor = big, large, great. As a further point of reference, morisenatha means high dragon.

righan/ghan = ? - I haven't found anything even similar to this section.

nan = revenge, vengeance, violent rage, especially violent rage in purpose of revenge

So, Morrighan'nan means Great (something) of Vengeance.

Now, what is Flemeth's lesser known title? Mother of Vengeance. She is all about taking revenge on the Evanuris for what they did to Mythal and to get her "reckoning that will shake the very heavens."

The similarities between Flemeth meddling with both Tyrdda's and Morrigan's pregnancies is also weird. I want to jump to the conclusion that Morrigan belongs to the same bloodline as Morrighan'nan and Tyrrda, and that it's the same line as the female-only Witches of the Wilds line who, through becoming Flemythal's vessels are needed for her vengeance, but that's conjecture and not yet 100% proven.

Anyway, do with this information what you will.

 

ETA: I just remembered Morrigan calls herself a High Priest if she drinks from the Well of Sorrows. High Priest of Mythal? High Priest of Vengeance? Might be a good enough bet.
