@lpslucasps well, it is ”sign language literature”, so there's that, but ”oral literature” is just to put it in the wider context of all the languages and literature as a phenomenon in general.
Polyglot City is the right instance for you, if you're interested in linguistics, languages, language learning and translating, or if you are multilingual or polyglot. All languages are allowed to flourish on our timelines. And of course you're free to talk about anything else besides languages, too. Make this your personal home!
