Slate is a fine-grained, metamorphic rock commonly used for roofing, flooring, and writing surfaces due to its durability and ability to be split into thin layers. In a broader sense, it also refers to a list of candidates or proposals, as in politics or business, or the act of scheduling events; today, it's often evoked in digital contexts like wiping the slate clean to symbolize a fresh start.
