Etymology: "Whimwhams" is the plural of "whimwham", a noun for a fanciful passing notion. The singular "whimwham" is built on the same pattern as "whim" and "whimsy", words that imply a sudden, capricious fancy. The reduplicated ending gives the word a playful, rattling sound, and it is used mostly for a light, unserious idea that passes quickly.
