Skeuomorphism is a design approach where digital interfaces retain certain elements from their real-world counterparts. For example, the notes app on iOS looks like a real-world notepad, with its leather binding and yellow lined pages, including a torn paper effect along the top where previous pages have been pulled out of the pad. (Obviously these pages do not exist in the digital world, and therefore this design choice is an attempt to insert "realism" into the UI for the purposes of familiarity == skeuomorphism)
