What does unzip mean?
Unzip means primarily to open a zipper or similar fastening: someone might unzip a coat, bag, suitcase, or tent flap. In computing, unzip means to extract files from a compressed archive, a usage that directly extends the idea of opening a sealed package. The word also has an informal figurative sense meaning to emerge or move suddenly, often with energy or surprise, as in a performer unzipping onto a stage. This expression is particularly associated with rapid, dramatic entrances, but it can describe people rushing out of a queue or doorway. The related noun is uncommon and denotes an act or instance of unzipping. Unzip is formed from the prefix un-, meaning to reverse or undo an action, and zip, the word for the fastener and the action of closing it. It is understood in both British and American English and is especially useful because it describes a familiar action with greater specificity than simply saying “open.”
