The golfer's conceit (3)

I believe the answer is:

ego

I'm a little stuck... Click here to teach me more about this clue!

'conceit' is the definition.
(I've seen this before)

'the golfer's' is the wordplay.
'EGO' is hidden within the letters.
However, I'm uncertain how this 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" .)

I've seen this clue in The Mirror.
