Other forms: rescuers
If you fall in a deep well, burst into flames, or walk off a cliff, you’re going to need a rescuer — someone to come and save you. A rescuer helps get people out of danger.
When a lifeguard swims out to save a drowning person, the lifeguard is a rescuer, and when a firefighter emerges from a burning house with a frightened puppy, the firefighter is a rescuer. In the book The Rescuers, mice help get other mice out of trouble. Someone who helps save a failing company or organization is another kind of rescuer, too: "The new CEO is a famous rescuer of troubled businesses."
