2612: iris Feb 8, 2022

The word 'iris' is the name for a flower as well as part of the eye. Both of these senses comes from the Ancient Greek ἶρις (îris) meaning 'rainbow', because this part of the eye deals with color, and the flower is named because it resembled the shape of the iris of the eye. More directly though, there is a Greek messenger deity who is both represented by the rainbow and gives certain significance to it, with some references using 'iris' to mean both messenger and rainbow. The root of this word means 'to twist' and is related to the English word 'wire', and the element iridium, which gives off many colors when dissolved.
