IPA: /rɪˈkʌvər/
KK: /rɪˈkʌvər/
A person who regains health, strength, or a lost item after a period of difficulty or illness.
After a long illness, she is finally a full recoverer and can return to her normal activities.
Recoverer → It is formed from "re-" (meaning again) and "cuperare" (from Latin, meaning to take back). The suffix "-er" indicates a person who performs an action. Thus, a recoverer is a person who takes something back again.
Think of someone who is taking something back 'again' ('re-') — that's why a recoverer is someone who helps to regain what was lost.
