Okay, so I googled a bunch of possible roots and found the root apo, meaning away or apart; and ap, meaning around or apart; so either away/apart from romantic attraction, or around/apart from romantic attraction; which sort of lines up with its official definition? This is just a temporary guess, once I find either who made it, the platform it was coined on, or just the general reasoning behind the structure of the word, I’ll add it here. Or if anyone knows that would be great, but I just posted this, I’m new, and there’s a good chance I did this wrong so yeah
