Dear piglet's cry in street; catch piglet's tail (10)
I believe the answer is:
sweetheart
'dear' is the definition.
(thesaurus)
'piglet's cry in street catch piglet's tail' is the wordplay.
I cannot quite understand how this works, but
'catch' could be 'hear' (I've seen this before) and 'hear' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for sweetheart that I've seen before include "flame?" , "boyfriend?" , "Darling" , "Darlin'"" , "Boy- or girlfriend" .)
