Did you know?

English has always drawn inspiration from fables and fairy tales, stories bursting with metaphors that help users get their verbiage just right: one may fall down a rabbit hole (thank you, Alice's Adventures in Wonderland), cry wolf (we see you, Aesop's Fables), or hope one day to meet one's Prince Charming (brava, Cinderella). The adjective Goldilocks is borrowed, of course, from Goldilocks and the Three Bears, a perennial favorite in which a little girl so-named for her golden hair finds the perfect balance between hot and cold, soft and hard, small and large—all in the home of unknowing strangers. Since the mid-1960s, English speakers have applied Goldilocks to all things regarded as perfectly balanced or happily medium. The word has specific applications in astronomy, with the phrase "Goldilocks zone" designating an area of planetary orbit in which temperatures are neither too hot nor too cold to support life.
