5 Elements (Bardism)

Calas/earth, water, breath, uvel, nwyvre
There are five elements: calas; water; air; fire; and nev. 

And others say thus:

3. There are five elements: earth, which is calas; fluidity, which is water and freshness; air, and hence all breathing, every voice and speech; fire, and hence all heat and light; and nwyvre, whence proceed all life, intelligence, knowledge, and power from will and desire.
