Is There a Pronoun That's Not Being Used for Something Else?

I saw the best suggestion i've seen from tweat by david boxenhorn. He suggests that, since there all these different pronouns, you get your he, they and if you just took the first letter from the pronouns that are out there, you could create your own universal one. So see what we'd geti you just dos the first letterlessly, she he it and they ther'ld be an, ass, aan, h and iwa. Could we have a word that sounds less like a notsy invasion? That's all y, just, i'm not asking a lot. I want, likeh a pronoun that's not being used for a completely different purpose
