Better advice about golf which might fetch you a bogey (9)
I believe the answer is:
fingertip
'better advice about golf which might fetch you a bogey' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'better advice about golf' is the wordplay.
'better' becomes 'finer' (I've seen this in another clue).
'advice' becomes 'tip' (a tip is a piece of advice).
'about' indicates putting letters inside.
'golf' becomes 'g' (phonetic alphabet: alpha, bravo, charlie etc.).
'finer'+'tip'='finertip'
'finertip' going around 'g' is 'FINGERTIP'.
Can you help me to learn more?
(Other definitions for fingertip that I've seen before include "One's used to feel" , "Pointer" , "One of the points" , "Digital extremity" , ""hunt the thimble" location in the end?" .)
