Primordial is the language of the primordials and some mortal races - particularly those that served under them like the elementals, beholders, the eldritch giants and the firenewts or those in areas of Chaos, like Flux. In this latter area, most speak Primordial as their first language. Some of the chaos archons also speak Primordial.

There are always two ways to say something in Primordial, one for the Primordial Lord, and one for the minion. The complexity and confusion does not end there, because many words have two to five ways to say them, again one way for the Primordial Lords, and the other ways for the minions. Thyrm took one word of each, none from the Primordial Lords usage, and created the Giant language. It is not as elegant and flowing as Primordial combinations of different words, but far easier to pick up for even the dumb.

Giant, Ignan, Jannti, Kuo-toa and Abyssal are derived from the Primordial language.
