Definition of agile

The word "agile" has its roots in Latin, where it was known as "agilis," which means "nimble" or "quick." The term originated in the 14th century and referred to someone or something that was able to move quickly and easily, often with a sense of lightness or flexibility. In a literal sense, agility referred to physical movement, such as the ability to dodge or weave around obstacles. Over time, the meaning of the word expanded to include mental and social agility, such as the ability to adapt quickly to changing circumstances or think on one's feet. It was not until the 1990s, in the context of software development, that the term "agile" took on its modern meaning, referring to a methodology or approach that emphasizes flexibility, adaptability, and rapid response to changing requirements.
