Geoff’s hat-trick, underlining rich sporting talent from the outset (5)
I believe the answer is:
hurst
'geoff's hat-trick underlining rich' is the definition.
I can't tell whether this definition defines the answer.
'sporting talent from the outset' is the wordplay.
'sporting' becomes 'hur' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'talent' becomes 'art' (I've seen this in another clue).
'from' indicates named letters should be taken away.
'the outset' becomes 'start' ('start' can be a synonym of 'outset').
'start' with 'art' removed is 'st'.
'hur'+'st'='HURST'
Can you help me to learn more?
(Other definitions for hurst that I've seen before include "wood" , "Wooded rise (archaic)" , "Grove" , "World Cup hero" , "A few ashes maybe" .)
