Coward caught by bird (6)
I believe the answer is:
craven
'coward' is the definition.
(I know that craven is a type of coward)
'caught by bird' is the wordplay.
'caught by' becomes 'c' (cricket abbreviation. I am not sure about the 'by' bit.).
'bird' becomes 'raven' (raven is a kind of bird).
'c'+'raven'='CRAVEN'
Can you help me to learn more?
(Other definitions for craven that I've seen before include "Cowardly, spineless" , "Chicken" , "Without backbone" , "Cowardly and fearful" , "Chicken-hearted" .)
