The word "cadre" refers to a small group of highly trained or experienced people who are capable of leading or organizing larger groups within an organization. It often pertains to the essential staff or key members within a broader system, particularly in a military or political context. This group usually has specialized skills and plays a critical role in the implementation of policies or actions.
The term "cadre" comes from the French word for "frame" or "framework," which is derived from the Latin "quadrum," meaning "square." It originally referred to a framework for military units and gradually came to describe a group with specific qualifications or training.
