IPA: /ˈrʌnˌbæk/
KK: /ˈrʌnˌbæk/
In football, it refers to the action of bringing the ball back after a kickoff, punt, or interception.
The player made an impressive runback after intercepting the pass.
Runback → The word is formed from "run" (from Old English "rinnan", meaning to flow or move swiftly) and "back" (from Old English "bæc", meaning the rear or reverse direction). The term "runback" refers to the act of running back or returning swiftly to a previous position.
Think of 'running' swiftly and 'going back' — that's how 'runback' means to return quickly.
