Esperanto is a language constructed by L. L. Zamenhof in 1887 to help foster communication between countries. It was designed to be an easy-to-learn international language. However, the vast majority of the vocabulary is based on Latinate roots, as 1887 was still the age of colonialism, so for non-Europeans it can be pretty hard to learn. Sadly, it didn't work as well as intended, thus spawning occasional mockery in modern media . Even then, it's still a thriving language within its own media, and there are a few people around the world who have grown up with Esperanto as a first language. Some stories set in The Future use Esperanto as if it had become the main language. It's also occasionally used As Long as It Sounds Foreign.
