graphite

Etymology

It is borrowed from German Graphit,^{[2][3][4][5][6]} coined in 1789 by the German mineralogist Abraham Gottlob Werner^[4][7][3] from Ancient Greek γράφω (gráphō, “to write”) and the mineral suffix -it, the German form of -ite,^[3][5][8] because the mineral was used to make pencils.^{[4][7][9][10][6]} The American Heritage Dictionary traces the Greek verb to the root Proto-Indo-European *gerbʰ-,^[11] which Barnhart connects with carve.^[3] The form French graphite is recorded in French from 1801, in Haüy,^[2] and Weekley derives the English word from the German or the French one.^[12]

Earliest recorded meaning

One of the crystalline forms of carbon, also called black lead or plumbago: 1796, in the second edition of Kirwan's Elements of Mineralogy.^[2][3][4][5]

Semantic evolution

The word came into English seven years after Werner coined the German name.^[3][2] The mineral is also known as black lead and plumbago.^[2][13] Its use as a solid lubricant for machinery is recorded from 1906.^[2] Collins lists its later uses: in pencils, crucibles and electrodes, as a moderator in nuclear reactors, and, as carbon fibre, as a tough, light material for sporting equipment.^[13] Merriam-Webster also records a verb graphite, to coat or impregnate with graphite.^[5]
