"A design feature that is carried forth from the original version of a product in order to make people feel comfortable with the new device. For example, the click sound on a digital camera comes from an audio clip; however, the original sound was the actual shutter opening and closing. Spokes on hubcaps are skeuomorphs, whereas spokes on early automobile wheels were necessary. Pronounced "skew-uh-morf." From the Greek Words Skeuos and Morph. "Skeuos" and "morph" mean "tool" and "shape," and the term originally referred to adornments that came from earlier Greek structures. For example, a decorative carving on a new building might replicate a form on an ancient temple that was structural."
