Goblin

Goblin vocabulary is shared by the goblin, bugbear, and hobgoblin races, even if the pronunciations, inflections, and usage differs wildly among them. When spoken by goblins, it is nearly incomprehensible to outsiders, and sounds more like high-pitched yapping. Among the martial hobgoblins, it takes the form of short, barked commands, while the bugbears speak their taunts with a sibilance not heard among the other goblinoid races.
It is an extremely flexible language, containing a plethora of terms related to subservience, fear, and death.
In Tian Xia, Goblin is the official language of the hobgoblin nation of Kaoling, although the dialect is different from the Goblin spoken in the Inner Sea region. Goblin speakers there also use the Tien alphabet.
