Little piggy possibly seen with kid and swine (6)
I believe the answer is:
toerag
'swine' is the definition.
I know nothing about this answer so I cannot judge whether this works.
'little piggy possibly seen with kid' is the wordplay.
'little piggy possibly' becomes 'toe' ('This little piggy went to market...').
'seen with' is a charade indicator (letters next to each other).
'kid' becomes 'rag' (both can mean to tease).
'toe'+'rag'='TOERAG'
'and' is the link.
Can you help me to learn more?
(Other definitions for toerag that I've seen before include "O, great! (anag) -- a worthless fellow" , "Despicable chap" , "Despicable person (slang)" , "despicable sort" , "Contemptible person (colloq.)" .)
