Sibiir

Sibiir is a fictional language featured in the science fiction television series The Expanse, based on the book series of the same name by James S.A. Corey. It is primarily spoken by the Belters, the inhabitants of the asteroid belt and outer planets.

Sibiir is a creole language, meaning it arose from the mixture of several pre-existing languages. In the context of the show, Sibiir developed from a pidgin used for communication between workers from different backgrounds who were colonizing the solar system. Over time, this pidgin stabilized and acquired its own grammar and vocabulary, becoming the distinct language known as Sibiir.

The base languages contributing to Sibiir include, but are not limited to, English, Spanish, French, German, Dutch, Mandarin Chinese, and various other Asian and African languages. This diverse linguistic ancestry is reflected in the vocabulary and grammar of Sibiir.

Sibiir serves several purposes in The Expanse narrative. Firstly, it adds to the world-building, making the Belter culture feel distinct and realistic. Secondly, it highlights the socio-economic divide between the Inner Planets (Earth and Mars) and the Belters, as the Belters are often marginalized and their language is looked down upon. Thirdly, it serves as a tool for Belter solidarity and resistance against Inner Planet oppression. They can communicate amongst themselves without being easily understood by Earthers or Martians.

The grammar of Sibiir, as presented in the series and supplemental materials, often features simplified verb conjugations and a preference for context to determine meaning. The language is constantly evolving, reflecting the Belters' ongoing struggles and adaptation to their harsh environment. The written form of Sibiir is rarely shown, but it is implied to exist, though its standardization is likely limited given the dispersed nature of Belter communities.
