Sea Common

Sea Common, or as Scarquans call it "Common," is the most prevalent language spoken by intelligent sea creatures capable of human-like speech. Even some intelligent creatures who cannot articular Sea Common at least understand it including many whales and some dolphins.
Sea Common was developed and spread by the Oshamni Empire. It's theoretically a combination of all Scarterran languages but more than of half of vocal words come from Mermish and the script is mostly derived from Asta'lash
