EDIT: I'm not looking at the notes for this or any of my posts for my own mental safety so please don't try to claim one that way. Submit to a popular mogai blog or make a flag and I'll see it. You can also tell me on my main (if you know it).
This is a personal collection of affixes that could be useful in coining terms. These are free to use in coining terms (as long as you're not an exclus/reg/transmed of any kind or violate my dni). I am also not any sort of linguistic scholar so I'm simply recording what I find without the guarantee that it's 100% accurate. I suggest looking these up to see more forms and words that use the affix before using so you have more context. I will edit this post to remove used ones I see. I'll also post more.
