Isn't fat novel entertaining like Don Quixote? (9)
I believe the answer is:
fantasist
'don quixote?' is the definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
'isn't fat novel entertaining like' is the wordplay.
'novel' indicates an anagram (letters in a new or novel order).
'entertaining' means one lot of letters goes inside another (inviting in, as for dinner).
'like' becomes 'as'.
'isnt'+'fat'='isntfat'
'isntfat' is an anagram of 'fantist'.
'fantist' going around 'as' is 'FANTASIST'.
Can you help me to learn more?
(Other definitions for fantasist that I've seen before include "Dreamer" , "Creator of very imaginative fiction" , "Walter Mitty type?" .)
