ConlangingFilm

Intern Lindsay here! Christine is correct, I can try to address any Tolkien-related questions, but I will say that I think his body of work has been instrumental in demonstrating just how many people enjoy constructed languages and are willing to engage closely with them. It's also easy to use Tolkien as an early model to demonstrate the power that conlangs can play in world building (particularly as his novels would not exist if not for the languages!) and I think this has contributed to their continued popularity, and inspired many conlangers (if not in an overly direct manner)

It is I, InternGirl!

Tolkien established that there was an orcish langauge, potentially several dialects of it as well, and that it's similar to a pidgin language (using bits of black speech and other borrowed words) For it to be spoken and used in the films though, the actual structure and vocabulary needed to be devised

Well, to be fair the slang is written in 'common tongue' which does exist in-verse and is spoken by some in Meereen. I do think it would be cooler in Valyrian though

It for sure shouldn't be there, it's just less weird than seeing 'English' pop up on a wall in Meereen

It seems the city must have some very well educated foreign-language graffiti artists, on both sides of the political spectrum!
