Etymology: "Voider" is a plain English formation: the adjective "void" (empty, without content, or invalid) with the agent suffix "-er," meaning a thing that does the action. In Middle English, "voider" was used for a receptacle, namely a basket or tray for clearing away leftover food and dishes from a table, a sense that survives in the older meaning of "voider" as a serving tray. The noun later took on the sense of something that makes void, so a thing that cancels or nullifies an entry, a ticket, or a transaction. The word therefore follows the same pattern as "sender" or "reader": a thing that performs the action named by its root. Here the root "void" came into English from Old French "voide," meaning empty, and it is the same base that gives us "avoid" and "devoid." Its earliest uses are in Middle English, which is where the source places the noun's first appearance.
