IPA: /ˌæntɪˈklɔkˌwaɪz/
KK: /æntɪˈklɔkˌwaɪz/
In a direction opposite to the way the hands of a clock move.
The children were instructed to turn anticlockwise to follow the path.
Anticlockwise is formed from "anti-" (meaning against) and "clockwise" (from "clock" which comes from Old English "clocca", meaning bell, and "wise" meaning manner or direction). The term describes a direction that is against the usual movement of the hands of a clock.
Think of moving 'against' ('anti-') the direction of a 'clock' — that's why anticlockwise means the opposite direction of how a clock moves.
