Duck or ducks from Slovenia (4)
I believe the answer is:
love
'duck' is the definition.
(duck and love can mean zero in sports)
'ducks from slovenia' is the wordplay.
'LOVE' is hidden in amongst the letters.
But, I'm not sure how this is indicated.
'or' acts as a link.
Can you help me to learn more?
(Other definitions for love that I've seen before include "Ardent emotion" , "No points" , "Passionate desire" , "Serenade" , "See 22" .)
