He doesn't believe in anything fancy (7)
I believe the answer is:
realist
'he doesn't believe in anything fancy' 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 'eal' and 'eal' is found within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for realist that I've seen before include "Plato, for example" , "Pragmatic person" , "Sensible and practical person" , "Retails for practical man" , "One has no fancy ideas" .)
