IPA: /ˈbækˌbɛnʧər/
KK: /ˈbækˌbɛnʧər/
A member of a legislative body, such as a parliament, who does not hold a position in the government and typically sits in the back rows.
The backbencher raised an important issue during the debate.
Backbencher → It is formed from "back" (from Old English "bæc", meaning the rear or behind) and "bencher" (from Middle English "benche", meaning a long seat or bench). A backbencher refers to a member of a legislative assembly who sits behind the front benches, typically those who are not in the government or opposition leadership positions.
Think of someone sitting at the 'back' ('back') of a 'bench' ('bencher') in a legislative assembly, which helps you remember that a backbencher is a member who is not in a leadership role.
