"Hymmnos is a language created by Akira Tsuchiya for Ar tonelico, a video game series (also known as Hymnos in the English localization of said games). According to the game world's history, it was formerly a common, spoken language, but has fallen out of use by the time of the main story's events (circa A.D. 3700). In modern times, Hymmnos is used only for songs that interface with ancient machinery. It appears to be a distant descendent of English with influences from Japanese, Sanskrit and German.
A defining feature of Hymmnos is that it puts a very strong emphasis on conveying the emotions of the speaker."
