The term 'OVER' is a four-letter word that means 'of higher rank than'. It is often used to describe someone who has authority or power OVER another person. For example, a manager may have authority OVER their employees, or a parent may have authority OVER their children. It can also be used to describe something that is greater in amount or size than something else. For example, a mountain may be higher than the surrounding hills, or a river may be wider than a stream.
