The act of looking into something again or examining it a second time, usually to find new information or clarify previous findings.
The police conducted a reinvestigation of the case after new evidence was discovered.
Reinvestigation → It is formed from "re-" (meaning again), "investigare" (from Latin, meaning to track or search), and "-tion" (meaning the action or process of). The word describes the action of searching or examining something again.
Think of 'again' ('re-') and 'searching' ('investigare') to remember that 'reinvestigation' means to search or examine something once more.
