Lovely girl netting most of vessel's carp (9)
I believe the answer is:
bellyache
'most of vessel's carp' is the definition.
The definition and answer can be both to do with communicating as well as being verbs in their base form.
Maybe you can see an association between them that I don't see?
'lovely girl netting' is the wordplay.
I cannot quite understand how this works, but
'girl' could be 'elly' and 'elly' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for bellyache that I've seen before include "protest" , "Moan noisily" , "Gripe" , "Gut pain" , "complain" .)
