The word "agile" refers to the ability to move quickly and easily. It often describes someone or something that is nimble and can adapt well to changes or challenges. In a broader context, "agile" can also refer to an approach or methodology that emphasizes flexibility and responsiveness, particularly in environments where requirements may change rapidly, such as in software development or project management.
The word "agile" comes from the Latin word "agilis," which means "quick" or "lively," derived from "agere," meaning "to do" or "to act." It entered the English language in the late 14th century.
