Hi
What does winning mean in
for examle
winning combination, winning duo.
Does it mean something like leader, number one, champion or the ones that make you win.
Many thanks
Literally it means that the thing has won a competition, award, etc.
Often it simply means that the thing is popular and successful, of high quality, attractive, etc. (in other words, it has the sort of qualities that would be expected to win a contest, to win support, to win friends, etc.).
many thanks Dozy
