IPA: /ˈæntɪˌlɒk/
KK: /ˈæntɪˌlɑk/
Relating to a braking system in vehicles that prevents the wheels from locking up during braking by adjusting the brake pressure on each wheel.
The car is equipped with an antilock braking system for better control during sudden stops.
Antilock is formed from "anti-" (meaning against) and "lock" (from Old English "locc", meaning to fasten or secure). The word describes a system that works against the locking of wheels during braking, preventing skidding.
Think of 'against' ('anti-') the action of 'locking' — that's why antilock refers to a system that prevents wheels from locking up.
