When designing the sound of the show, extra care was taken to make sure that the language felt just as real as the ship designs.
Belter Creole, or Lang Belter, was developed with thought to the natural evolution in language that occurs when people of a wide base of cultures live and work in close proximity.
The Belt was a melting pot for the most intrepid of humanity, a patchwork of peoples from all parts of the world and all walks of life, as it grew from isolated colonies and outposts to the emergent nation we see in the show. Like many patois languages, its core basis was supplemented by a mix of other linguistic influences.
In this case, a base of English was modified with elements of Germanic, Chinese, Slavic, Latin, Indic and Niger-Congo languages, giving us the wonderfully rough and contrasting Belter language we're treated to.
