What is the full meaning of orbit?

Could you please elaborate on the comprehensive definition of the term 'orbit'? I understand it's related to the path of an object around a larger one, but I'm curious about the specifics of how it's defined and used in various contexts. Does it solely apply to celestial bodies, or can it be applied to other types of motion as well? I'm particularly interested in any nuances or exceptions to the general meaning of orbit that may exist.
