I suddenly realised I have no idea how to refer to the round objects used in a game of baseball
baseballs? doesn’t sound right
baseball balls? surely not
That’s what they are, Argumate. One is a baseball, more are baseballs.
“About the size of a baseball.” “He hit a baseball over the fence.” Etc.
I feel like maybe you don’t belong in America (or Japan).
(Nah I’m just kidding, Japanese would probably use some counter so the plural form wouldn’t be “baseballs” (per se).)
