Love of football (3)
I believe the answer is:
nil
This might be a double definition.
'love' is the first definition.
(I've seen this before)
'football' is the second definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for nil that I've seen before include "Latin zero" , "Love" , "Zero, zilch" , "none" , "Score of nought" .)
