foursome
UK: ˈfɔːsəm | US: ˈfɔːrsəm
n. a group of four people or things, especially in sports or games
n. (Golf) a match between two teams of two players each
The word "foursome" combines "four," from Old English "fēower," meaning the number 4, and the suffix "-some," derived from Old English "-sum," used to form collective nouns indicating a group. The term originally described any group of four but later specialized in sports contexts, particularly golf, where it denotes a two-team match with two players per team. The logic is straightforward: "four" defines quantity, while "-some" aggregates it into a unit.
