IPA: /ˈʌndərˌspɪn/
KK: /ˈʌndərˌspɪn/
A type of spin applied to a ball that causes it to rotate backward as it moves forward, often used in sports like tennis or table tennis.
The player used an underspin to make the ball bounce lower and confuse his opponent.
Underspin → It is formed from "under-" (meaning beneath or below) and "spin" (from Old English "spinnan", meaning to twist or turn). The word "underspin" refers to a type of spin applied to a ball that causes it to move in a specific way, typically in sports, suggesting a motion that occurs beneath the normal trajectory.
Think of something that is 'beneath' ('under-') and 'twisting' ('spin') — that's how underspin describes a specific type of spin that affects the movement of a ball.
