Be unsuccessful getting rid of large peacock (3)
I believe the answer is:
fop
'be' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for fop that I've seen before include "A man much concerned with his appearance, a dandy" , "Man excessively concerned with fashion" , "he enjoys the finest dressing" , "Man excessively concerned with his appearance" , "One affected" .)
