However, there are a few instances of other languages being used:
* Trigedasleng: This is a fictional language spoken by the Grounders, a group of people who lived on Earth after the apocalypse. It has a unique vocabulary and grammar, and its creation was a collaborative effort between the show's writers, language experts, and actors.
* Other languages: While not as prominent as Trigedasleng, characters occasionally speak other languages like Spanish, German, and even Latin. These instances are often used for character development or to highlight cultural influences.
Overall, the main language spoken on The 100 is English, but the use of Trigedasleng and other languages adds depth and complexity to the show's world-building.
