Flirtatious parrot won’t keep quiet (3)
I believe the answer is:
coy
'flirtatious' is the definition.
(I've seen this in another clue)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for coy that I've seen before include "Pretending modesty" , "Reserved" , "Military team in brief" , "Pretending to be shy or bashful" , "Pretending shyness" .)
