The golfer's conceit (3)
I believe the answer is:
ego
'conceit' is the definition.
(I've seen this before)
'the golfer's' is the wordplay.
'EGO' is hidden in amongst the letters.
But, I'm not sure how the hidden word is indicated.
Can you help me to learn more?
(Other definitions for ego that I've seen before include "One's self image" , "One's self-image" , "Personal pride" , "Conceit - the Latin "I"" , "Conscious mind" .)
