Badminton doesn't have the term set. A game is 21 points and a match is a best of 3. Compared to tennis, a match is a single set (a set of games). https://en.wikipedia.org/wiki/Badminton#Comparison_with_tennis I also find it easier to say let's play a set (best of 3) than let's play a match. My friend, though, argues that a set is a game (up to 21), and he is confused by this link https://www.masterbadminton.com/badminton-terms.html What do you think?
