Appeal of swallow nesting in porch (8)
I believe the answer is:
entreaty
'appeal' is the definition.
(I know that appeal can be written as entreaty)
'swallow nesting in porch' is the wordplay.
'swallow' becomes 'eat' (swallow can mean to consume or eat up).
'nesting in' indicates putting letters inside.
'porch' becomes 'entry' (I can't explain this - if you can you should give a lot more credence to this answer).
'eat' placed into 'entry' is 'ENTREATY'.
'of' is the link.
Can you help me to learn more?
(Other definitions for entreaty that I've seen before include "Teeny rat (anag.)" , "suit" , "Appeal" , "An earnest or emotional request" , "Earnest plea" .)
