George Best estate has raised a fortune (9)
I believe the answer is:
autopilot
'george' is the definition.
(I've seen this before)
'best estate has raised a fortune' is the wordplay.
I cannot really understand how this works, but
'best' could be 'top' (top can mean the very best) and 'top' is found within the answer.
'a' is found in the answer.
'fortune' could be 'lot' (as in a person's lot in life) and 'lot' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for autopilot that I've seen before include "Plane on ...... is under automatic control" , "Robot flier?" , "George (sl.)" , "control bypassing human intervention" , "Action without self-awareness" .)
