The story of the word

στερεός means solid in the sense of having three dimensions, which is why Charles Wheatstone named his 1838 stereoscope from it: two flat pictures, one per eye, adding up to depth. Stereophonic applies the same trick to hearing. Stereotype came out of the printing trade, where it was a solid cast plate of a whole page, long before it meant a fixed idea about people.
