Serusan

Serusan (or Serosian common) was a shorthand language used as a common trade language by shallow-water races. It was a distinctly an undersea tongue, and contained dolphins' clicks and whistles, words from the sahuagin language language, the aquatic elvish tongue , and the kuo-toan language, it also included some parts from the aquan language, which was used by locathah , merfolk , and shalarin. All these races could speak and understand Serusan, but unless fluent in it as a separate language, they could only grasp the most basic meanings.
