Word History

Etymology

borrowed from German Sphalerit, from Greek sphalerós "causing a slip, precarious, fallible, unreliable, deceptive" (derivative, with the adjective suffix -eros, from the base of spállein "to bring down, catch off balance, lead astray") + German -it -ite entry 1; spállein going back to Indo-European *(s)g^whh₂el- "make a wrong step, stumble," whence also Sanskrit skhálate "[s/he] stumbles, trips," Armenian sxalem "[I] stumble, go astray"

Note: The term Sphalerit was introduced by the German mineralogist Ernst Friedrich Glocker (1793-1858) in Generum et specierum mineralium, secundum ordines naturales digestorum synopsis (Halle, 1847), p. 17. Glocker explains the choice of name as follows: "Nomen Sphalerites, formatum ex voce σφαλερὸς, decipiens s. fallax, eandem significationem habet, quae germanico nomini Blende inest. Saepissime enim varietates hujus generis splendore eximio ornatae a metallorum fossoribus pro aere quodam pretioso habitae sunt." ("The name Sphalerites, formed from the word sphalerós, deceptive or misleading, has the same meaning as the German noun Blende. For varieties of this genus, marked by exceptional brilliance, are very often taken as some valuable ore by miners of metals."). See also blende.
