Golfer upset about bad take (7)
I believe the answer is:
snaffle
'take' is the definition.
(I know this)
'golfer upset about bad' is the wordplay.
'golfer' becomes 'els' (Ernie Els - former number one professional golfer).
'upset' shows that the letters should be reversed in order.
'about' is an insertion indicator.
'bad' becomes 'naff' (I can't explain this - if you can you should believe this answer much more).
'els' reversed gives 'sle'.
'sle' placed around 'naff' is 'SNAFFLE'.
Can you help me to learn more?
(Other definitions for snaffle that I've seen before include "Kind of bit - take without permission" , "Appropriate" , "A bit; filch" , "Horse's bit" , "Capture" .)
