He gets priceless ideas (11)
I believe the answer is:
freethinker
'he gets priceless ideas' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'he' is the wordplay.
I cannot really understand how this works, but
'he' could be 'free' and 'free' is found in the answer.
The remaining letters 'thinker' 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 freethinker that I've seen before include "Rationalist" , "I take a rational view" , "Person with their own religious beliefs etc" , "Person not holding generally accepted beliefs" , "Someone with opinions formed independently" .)
