The daisy is named for getting up. In Old English it was dæges ēage, the day’s eye, because it folds its petals shut at dusk and opens them again in the morning, and over a few centuries the eye wore down to the y at the end of daisy. Most flowers were named for how they look or what they were good for; this one was named for a habit, the way a street might know a neighbour as the one whose curtains are always open first. Hardly anyone who says the word now hears the eye in it, and the daisy goes on doing the thing it was named for anyway, every morning, without needing anyone to remember why.
