where did it originate, and why?
come to think of it, i also kinda wonder where the ¿...? and ¡...! in Spanish originated.... Huh. Punctuation is weird
also aren't there some languages that use ,,..." instead of english's "..."? and french, again being unusual, uses «...» for the same purpose
and Japanese uses 「...」, but that's kinda just an entirely different writing system with different rules so it feels more expected that punctuation would be different?
