Fish possibly bronze, or maybe amber (5)
I believe the answer is:
bream
'fish' is the definition.
(bream is a kind of fish)
'bronze or maybe amber' is the wordplay.
'amber' anagrams to 'BREAM'.
Though, I am unsure how this is indicated.
'possibly' acts as a link.
Can you help me to learn more?
(Other definitions for bream that I've seen before include "Carp relative" , "Bar me from the freshwater fish" , "Broad, thin fish" , "Amber kind of fish" , "Fish of the carp family" .)
