Etimology of Whimsical

The word "whimsical" is an adjective that means full of or characterized by whims, which are odd ideas that usually occur to you very suddenly. It can also mean tending toward odd or unpredictable behavior. According to Merriam-Webster, "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.

The word "whimsy" itself means "whimsical device, trifle," and its origin is unknown, but it may be from Scandinavian. The word "whimsical" was first used in the 1650s and is derived from "whimsy" with the addition of the suffix "-ical".
