Someone who boxes fresh curries (7)
I believe the answer is:
cruiser
'someone who boxes' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'fresh curries' is the wordplay.
'fresh' is an anagram indicator (a fresh re-ordering of the letters).
'curries' with letters rearranged gives 'CRUISER'.
Can you help me to learn more?
(Other definitions for cruiser that I've seen before include "Warship - pleasure boat - boxing weight" , "Leisure yacht; warship" , "Speedy warship" , "Relatively fast warship" , "Ship" .)
