IPA: /ˌriːɪˈnæktmənt/
KK: /riˈnæktmənt/
The act of performing or recreating a past event, often for educational or entertainment purposes.
The community organized a reenactment of the historic battle to educate people about their local history.
Reenactment → It is formed from "re-" (meaning again) and "enact" (from Latin "enactare", meaning to put into action or to perform). The word refers to the act of performing something again, often a historical event.
Think of doing something 'again' ('re-') that has been 'performed' ('enact') before — that's why reenactment means to perform again.
