Brilliant Germany gutted to accept defeat (6)
I believe the answer is:
glossy
'brilliant' is the definition.
Both the definition and answer are adjectives. Maybe there's an association between them I don't understand?
'germany gutted to accept defeat' is the wordplay.
'gutted' means to remove the middle letters (to gut something is to remove its insides).
'to accept' means one lot of letters goes inside another.
'defeat' becomes 'loss' (I've seen this before).
'germany' with its middle removed is 'gy'.
'gy' enclosing 'loss' is 'GLOSSY'.
Can you help me to learn more?
(Other definitions for glossy that I've seen before include "Smooth, shiny" , "Smooth and shining" , "Magazine printed on good quality paper" , "Highly polished" , "Kind of magazine" .)
