Hovering means moving through the air without touching anything or going anywhere fast.
When people say something is hovering, they usually mean that it's floating around an idea or decision instead of making a choice. For example, if you're trying to decide whether to buy a new car and can't make up your mind, someone might say, "You've been hovering over this decision for weeks." They mean that you're not quite committed one way or the other, but keeping an open mind.
To float in the air.
Example: The hummingbird hovered by the plant.
The act of one who hovers.
