He takes an artistic delight in eating out (6)
I believe the answer is:
etcher
'he takes an artistic delight in eating out' 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 see how this works, but
'he' could be 'che' and 'che' is found within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for etcher that I've seen before include "Maybe she makes engravings" , "Creative artist" , "Cutter" , "One sharply scores" , "Artist such as Rembrandt" .)
