What would be an example of a novel idea?

An example of a novel idea is an original and innovative concept. This definition captures the essence of what makes an idea "novel"—it is new, unique, and introduces something that has not been previously conceived or widely known. Novel ideas often challenge existing paradigms, offer fresh perspectives, or present solutions that have not been considered before. By contrast, a well-established theory represents an accepted idea that has been thoroughly examined, a minor variation of an old idea suggests only a slight adjustment rather than a completely new thought, and a common belief reflects widespread acceptance without necessarily contributing anything new or innovative. Thus, an original and innovative concept stands out as the embodiment of novelty.
