Does it show irritation at having been caught? (7)
I believe the answer is:
snapper
'it show irritation at having been caught?' is the definition.
The definition suggests a singular noun which matches the answer.
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for snapper that I've seen before include "sharp-toothed fish" , "Fish; photographer" , "Person photographing" , "Fish; marine turtle" , "(Often red) food fish" .)
