IPA: //ˈɡraʊndər//
KK: /ˈgraʊndər/
In baseball, a type of hit where the ball is hit along the ground rather than in the air.
The player hit a grounder that rolled past the infielders.
Grounder → The word is formed from "ground" (from Old English *grund*, meaning the solid surface of the earth) and "-er" (meaning a person who). A grounder refers to a person or thing that is related to the ground, often used in sports to describe a type of hit or play that stays low to the ground.
Think of someone or something that is related to the 'ground' — the '-er' indicates a person or thing associated with it. A grounder is something that stays close to the ground.
