Men wise in imagination (4)
I believe the answer is:
'men' is the definition.
(I have seen 'Wise Men' mean 'magi' so perhaps 'men' could also mean 'magi')
'wise in imagination' is the wordplay.
'MAGI' is hidden in amongst the letters.
However, I am not sure how the hidden word is indicated.
Can you help me to learn more?
(Other definitions for magi that I've seen before include "Travellers in NT" , "The sages who visited Jesus and Mary and Joseph shortly after Jesus was born" , "Three Wise Men of the Bible" , "Star witnesses" , "Bearers of gold, frankincense and myrrh?" .)
