Approval after chap (sailor) delivers fish (5,3)
I believe the answer is:
manta ray
'fish' is the definition.
(manta ray is a kind of fish)
'approval after chap sailor' is the wordplay.
I cannot quite see how this works, but
'approval' could be 'ma' (MA is an example) and 'ma' is located in the answer.
'chap' could be 'ara' and 'ara' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
'delivers' acts as a link.
Can you help me to learn more?
(Other definitions for manta ray that I've seen before include "Devilfish" , "large fish" .)
