Etymology: Charcoal was once understood as "turned coal." Middle English "charcole" combined "charren," meaning "to change or turn," with "cole," meaning coal. The idea was that coal, heated and transformed by fire, became something new: the black, light, brittle material that burns without the smoke and sulphur of raw coal. The word's first part is the reason it sounds like "char," the scorching of wood or food, but the two are not the same origin. The "char" in charcoal comes from the older verb "chare" or "charren," meaning to turn or change, which is a different word from the one meaning to burn lightly. Folk readers often assume the word simply means coal that has been charred, and the English name reflects that reading, though the older sense was about transformation.

Synonyms: carbon, char, coal
