IPA: //ˈɡraʊndaʊt//
KK: /ˈgraʊndˌaʊt/
In baseball, a situation where a batter is out after hitting a ball that rolls along the ground to a fielder.
The player made a quick throw to first base to get the runner out on a groundout.
Groundout → The word is formed from "ground" (from Old English "grund", meaning the bottom or surface of the earth) and "out" (meaning away from the inside or center). The term "groundout" refers to a baseball play where a batter hits the ball and it rolls on the ground, resulting in an out.
Think of the 'ground' as the surface where the ball rolls and 'out' indicating the result of the play — that's how 'groundout' describes a play where the ball is hit on the ground and results in an out.
