Goblin is the language used by the goblins. Goblin is generally written with the Common alphabet. However, most goblins have mastered a myriad of other languages including Orcish and Common in order to trade with members of the big factions.
Every goblin has a given name and a family name. The family names portray some ancestor's achievement, though a goblin may take a new family name if he feels he has made an accomplishment that outstrips that of his eponymous forebear.
