Among my innumerable pronoun sets is ꙮ/ꙮm/ꙮr/ꙮrs/ꙮself. I have never actually been called these pronouns because everyone gravitates towards she/her and xe/xem, which are my favorite sets; but ꙮ/ꙮm still remain listed in case someone would be so unimaginably based as to actually use them.
How do you type ꙮ/ꙮm/ꙮr? Well either you copy-paste, or you know how to type Unicode characters (I can’t figure this out TBH), or you have a custom keyboard layout that maybe lets you type the Cyrillic multiocular O by hitting AltGr+O or something — or you perhaps do what I do, which is that I use the custom dictionary feature of my Japanese IME such that ⟨Se⟩ brings up ⟨ꙮ⟩, likewise ⟨Sm⟩ → ⟨ꙮm⟩, ⟨Sr⟩ → ⟨ꙮr⟩, ⟨Sz⟩ → ⟨ꙮrs⟩, and ⟨Ss⟩ → ⟨ꙮself⟩.
Alright, the obvious next question: how do you actually read ꙮ/ꙮm/ꙮr out loud???
—The answer is that nothing is necessarily stopping you from reading ꙮ/ꙮm/ꙮr in any way you like, in fact nothing even stipulates that you need to use the inflections ꙮm/ꙮr rather than any other inflectional pattern; but nevertheless I personally prefer the readings seraph/seraphim/seraphyr/seraphyrs/seraphimself… Get it? It’s like, you reinterpret the Hebrew masculine plural suffix as an analogy of him and them, and then you derive the possessive forms from her and hers with spelling influenced by zephyr and xyr. I like to imagine that I am clever sometimes, huh!
If one is to use the seraph/seraphim readings, however, then one may also use any number of reduced forms in unstressed positions, to more clearly signal the word’s pronominality: /s/ may be rendered as [z] and /f/ may be rendered as [v], and /ɛɹə/ may be rendered as [ɛɹ̠ʷ] [ɹ̠ʷ] [ə] [ə̥] or may be deleted entirely; and we may observe resyllabification effects with adjacent words as well. The exact form of reduction of ꙮ/ꙮm/ꙮr depends on how extreme the reduction is on a spectrum, as well as the environment surrounding the reduced form — such as whether it’s before or after a vowel vs consonant, before or after a voiced or voiceless sound, things like that.
In any case, you might think that it’s a bit counterintuitive to get “seraph” and “seraphim” from ꙮ/ꙮm, at least if you’re unaware of the fact that the Cyrillic multiocular O represents the many eyes of the seraphim… But if that’s the case, then you can simply add ruby characters: ꙮ, ꙮm, ꙮr, ꙮrs, ꙮself. And if you’re writing on a website or program that does not support ruby characters, then that’s their problem, not yours.
