Important match sought by one on safari? (3,4)
I believe the answer is:
big game
This clue might be a double definition.
'important match' is the first definition.
(a big sports game)
'sought by one on safari?' is the second definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
Can you help me to learn more?
(Other definitions for big game that I've seen before include "International?" , "Cup Final perhaps" , "aim of African sportsmen" , "supplier of trophies" , "Maybe cup final" .)
