I appreciate Ann Leckie using e/em/eir, but that's the one I think works much better in voice than print. In print I almost wish it were directly printed with a schwa: ə/əm/əir. Keep getting cap-E Ə confused with Long E (as "I" always is) and I realize that's mostly a me problem and schwa would confuse more readers than it helped (me), but I find it an interesting observation and schwa is cool.
ə/əm/əir is also not an option on pronoun.is, but should be
I guess there probably is a split between if E should be Long E or schwa. I don't think Long E works right, but on thinking about it, I realize some probably prefer that too. Interesting.
