Trade is a shared international language known by many species throughout the SARPiverse. It is a national language of the Democratic Imperium of Nepleslia and one of two national languages of the Yamatai Star Empire (the other being Yamataigo (邪馬台語)). Sometimes Trade is called Nepleslian. Trade is based on the real-world English language.

For a list of all known languages spoken in the SARPiverse, see Languages.

Since Star Army is an English-language site, having most characters speak an English-derived dialect makes it easy for our characters to communicate.
