In his net, a keen angler can catch a fish? (4)
I believe the answer is:
take
'in his net a keen angler can catch a fish?' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
'in his net a keen' is the wordplay.
'in' indicates the answer is hidden within the clue.
'TAKE' can be found hidden inside 'his net a keen'.
Can you help me to learn more?
(Other definitions for take that I've seen before include "Perspective" , "Receive willingly" , "Appropriate" , "Approach" , "bear" .)
