The word "during" is a preposition that indicates a specific time period in which something happens. It is used to refer to events or actions that take place at the same time as another event or action.
The word "during" comes from the Middle English "during," which is derived from the Old French word "durant," the present participle of "durre," meaning "to last." This is ultimately rooted in the Latin word "durare," which means "to last, to endure."
