A process of giving a second or additional injection, often used in medical or technical contexts.
The doctor recommended a reinjection to ensure the treatment was effective.
Reinjection → It is formed from "re-" (meaning again) and "injection" (from Latin "iniectio", meaning to throw in). The word "reinjection" means the act of throwing something in again, typically referring to the reintroduction of a substance into a system.
Think of 'again' ('re-') and 'throwing in' ('injection') to remember that reinjection means to throw something in again.
