IPA: /ˈbækˌdɔːr/
KK: /ˈbækˌdɔr/
Referring to something that is secretive or done in a hidden way, often used in contexts like sports or clandestine activities.
The team executed a backdoor play to surprise their opponents.
Backdoor → It is formed from "back" (from Old English "bæc", meaning the rear or behind) and "door" (from Old English "duru", meaning an entrance or opening). The word "backdoor" refers to a secondary entrance at the rear of a building, often used for discreet access.
Think of the 'rear' ('back') of a building where a 'door' is located — that's why a backdoor is an entrance at the back.
