Person having a flutter fully recovered (6)
I believe the answer is:
better
'recovered' is the definition.
(I've seen this before)
'person having a flutter fully' is the wordplay.
I cannot really understand how this works, but
'flutter' could be 'bet' (flutter can mean a small bet) and 'bet' is found in the answer.
The remaining letters 'ter' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for better that I've seen before include "Speculator" , "More able" , "Recovered from illness - more satisfactory" , "he will take risks" , "On the mend" .)
