Background / Comments
Our word comes from sigma, the 18th letter of the Greek alphabet. I was puzzled at the first and second definitions, because they quite different, but it turns out that the sigma has a form shaped like the Roman ‘C’, but sigma is normally brought into English as an ‘S’ – and thus the two definitions. While it can refer to the curve in a graph, our word is normally used these days to refer to the curve in the large intestine.
