Additional protection on the cricket field (5,5)
I believe the answer is:
extra cover
'cricket field' is the definition.
The definition suggests a singular noun which matches the answer.
'additional protection on' is the wordplay.
'additional' becomes 'extra' (I've seen this before).
'protection' becomes 'cover' (I've seen this in another clue).
'on' means one lot of letters go next to another.
'extra'+'cover'='EXTRA COVER'
'the' acts as a link.
Can you help me to learn more?
(Other definitions for extra cover that I've seen before include "Cricketer" , "Greater insurance" , "Cricket fielder - more insurance?" .)
