Etymology: "Lilypad" is simply the closed-up form of "lily pad", a compound of "lily" and "pad". The "pad" half is the older and more interesting part: it comes from a Middle English word for a soft cushion or bundle, and its sense of a flat, broad surface is what makes the name fit a floating leaf. Lilies, meanwhile, have a long history in English, and the plant name was applied to the water plants that share the familiar broad, flat leaves. The combined form reflects how English compounds tend to settle over time. Many open compounds are first written with a space and later close up into a single word, and "lilypad" is one of the forms that has done so. Both spellings are in use, and the meaning is the same.
