Ingenuity is the quality of being clever, original, and inventive, often in the process of applying ideas to solve problems or meet challenges. Ingenuity (Ingenium) is the root Latin word for engineering. For example, the process of figuring out how to cross a mountain stream using a fallen log, building an airplane model from a sheet of paper, or starting a new company in a foreign culture all involve the exercising of ingenuity. Human ingenuity has led to various technological developments through applied science, and can also be seen in the development of new social organizations, institutions, and relationships. Ingenuity involves the most complex human thought processes, bringing together our thinking and acting both individually and collectively to take advantage of opportunities and/or overcome problems.
