The Greek roots

to write, scratch

Literally: the writing stone

The story of the word

Abraham Gottlob Werner named it in 1789, choosing the Greek verb for writing because the mineral's whole use was making marks. Until then it was called plumbago or black lead, and the mistake survives in the phrase lead pencil, which contains no lead at all. Pencil graphite from the Borrowdale mine in Cumbria was so valuable it was guarded by armed men.
