Check for bad light in cricket, perhaps (4,5)
I believe the answer is:
test match
'cricket perhaps' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'check for bad light' is the wordplay.
'check for' becomes 'test' (synonyms).
'bad light' becomes 'match' (match is a kind of light. I am not sure about the 'bad' bit.).
'test'+'match'='TEST MATCH'
'in' is the link.
Can you help me to learn more?
(Other definitions for test match that I've seen before include "Strike a light!" , "International meeting" , "Sort of game" , "Big game in India?" , "important fixture" .)
