Swoop is an action that involves a sudden, quick movement. It can be used to describe an ATTACK, a FALL, a DROP, a PLUNGE, a DIVE, or a POUNCE. All of these words have the same meaning, but they are used in different contexts. For example, an ATTACK is usually used to describe a physical assault, while a FALL is used to describe a downward movement. A DROP is used to describe a sudden decrease in height, a PLUNGE is used to describe a rapid descent, a DIVE is used to describe a steep DIVE into water, and a POUNCE is used to describe a sudden jump onto something.
