quartz

Pronunciation

• UK: /k(w)ɔːts/^[1]
• US: /k(w)ɔɹts/^[1]

Etymology

It is borrowed from German Quarz,^{[2][3][4][5][6]} earlier also Querz, first recorded in the first half of the 14th century as a Middle High German quarz of Bohemia,^[2][7] where it was a term of the mining trade.^[8] Barnhart and Etymonline give the Middle High German forms as twarc, quarc and zwarc.^[4][3] The origin of the German word is uncertain.^[2][8][7][9] The OED, Pfeifer and Weekley suggest a pet form, with the suffix -z as in Heinz for Heinrich, of Middle High German querch, a variant of twerc (“dwarf”) (see dwarf):^[2][7][10] miners blamed mountain spirits for a mineral that yielded no ore, as with cobalt and nickel,^[7] and the OED compares Norwegian dvergstein (“quartz, literally dwarf-stone”).^[2] Others derive it from a West Slavic word for "hard":^[4][3][5][6] Polish kwardy in Polish dialect, a variant of twardy (“hard”),^{[6][11][2][12]} compared with Czech tvrdý (“hard”),^[6][12][13] which the OED gives as an alternative etymology.^[2] The Slavic words are related to Lithuanian tvirtas (“hard, firm”).^[2][12] Kluge instead connects it with chert in English dialect and Swedish kart (“small stone”) in Swedish dialect, and reconstructs Proto-Germanic *kwarta-.^[8] From German come also Italian quarzo (1550), French quartz (1749), Swedish kvarts (1685) and Dutch kwarts.^[2][7][10]

Earliest recorded meaning

The rock-forming mineral made of silica: Merriam-Webster dates it to about 1631,^[13] the OED to 1676, in Elisha Coles's English Dictionary,^[2] and Barnhart and Etymonline to 1756.^[4][3]

Semantic evolution

The word has kept its mineralogical meaning in English.^[2][6] In American slang of about 1900 quartz could also mean money.^[14]
