Gascon goes back in hat (7)
I believe the answer is:
boaster
This might be a double definition.
'gascon' is the first definition.
Both the answer and definition are singular nouns.
Maybe you can see an association between them that I can't see?
'back in hat' is the second definition.
The answer and definition can be both people as well as being singular nouns.
Maybe there's an association between them I don't understand?
'goes' is the link.
Can you help me to learn more?
(Other definitions for boaster that I've seen before include "Peacock" , "swanky one" , "Braggart, blowhard" , "Braggart, loud-mouth" , "Person who continually brags" .)
