Did you know?
Whimsical and the related nouns whim and whimsy all ultimately derive from whim-wham, a noun from the early 16th century that originally referred to an ornamental object or trinket. Later whim-wham, with its fun sound, came to refer to a fantastic notion or odd fancy. The word's origin isn't clear, but it's worth noting that the similar-sounding flimflam had, in its earliest use, a similar meaning referring to an odd or nonsensical idea or tale. Whim naturally came about as a shortened form of whim-wham, and whimsy and whimsical eventually followed. Whimsical now describes more than just decisions made impulsively, but things resulting from an unrestrained imagination, as in "whimsical children's book characters."
