The conlang 'Jeïos' [dʒɛɪ'ʝiːɔs] (or [dʒɛɪɔs]) was created in the year 2012 by Marvin Johanning. The name "Jeïos" comes from his username "Jeytas". It was created in the year 2010. He and his friend wanted to make a radio show on YouTube, so they had to think of a name. They chose to combine both of their names and ended up with Jeitas. When they tried that name, it was already used, so they switched the "i" with a "y" and Jeytas was the end result. Three years later in school, in chemistry class, Marvin was bored so he started working on a little language. He had to think of a name for it, so he took his username and changed it a bit.
