The Greek roots
Literally: “solid stamping”
The story of the word
The parent word was a printing term: a stereotype was a solid metal plate cast from a page of type, so the same page could be struck again and again without resetting. Nineteenth-century psychiatrists borrowed the image for behaviour that repeats identically. The social sense of stereotype, a fixed idea of a group, came later still, through Walter Lippmann in 1922.
