Someone was asking about this a little bit ago, and I was finally able to find the old post.
This is a list compiled off an old thread on OKA of what various angelkin remembered the angelic language being like. I think in total there were between 6-10 contributers to this, though I can't remember who they all were, and as OKA no longer exists, i can't go back and check.
Naâher (short vowel sounds, emphasis on second syllable, second syllable can be said either âherâ or âhairâ)
*means âbeloved younger siblingâ (used in context, it can mean either brother or sister)
Khaâshet (short vowel sounds, emphasis on second syllable)
*means âbeloved older siblingâ (used in context, it can mean either brother or sister)

*I donât know what it meansâŚyet. But I was feeling weird, like someone was watching me, and I said it, and whatever was watching me instantly vanished. So I believe it is some sort of phrase of blessing or protectionâŚheck, it might even be cussing, who knows.

There are possibly a few different dialects going on here, but this is a pretty good sample of what myself and several others remember the angelic language being like.
I've also submitted this to STFUO since they are a linguits and i'd love to get a real critical analysis on this.
