Little rascal learning to beg (7)
I believe the answer is:
implore
'beg' is the definition.
(synonyms)
'little rascal learning' is the wordplay.
'little rascal' becomes 'imp'.
'learning' becomes 'lore' (I've seen this before).
'imp'+'lore'='IMPLORE'
'to' acts as a link.
(Other definitions for implore that I've seen before include "Beg earnestly, beseech" , "More lip (anag)" , "Ask earnestly" , "Beg earnestly, entreat" , "Beg earnestly, plead" .)
