Rescuer → It is formed from "re-" (meaning again) and "cuer" (from Latin "cūrare", meaning to care for or heal). The word "rescuer" refers to someone who cares for or saves someone again, typically from danger or distress.
Think of someone who 'cares for' ('cūrare') someone 'again' ('re-') — that's why a rescuer is someone who saves or helps someone in need.
