Plead for a fairy tale? (7)
I believe the answer is:
implore
'plead for' is the definition.
(thesaurus)
'a fairy tale?' is the wordplay.
'a fairy' becomes 'imp' (imp is a kind of fairy).
'tale?' becomes 'lore' (I can't explain this - if you can you should give a lot more credence to this answer).
'imp'+'lore'='IMPLORE'
Can you help me to learn more?
(Other definitions for implore that I've seen before include "press" , "Beg earnestly, entreat" , "Beg earnestly, plead" , "Beg earnestly, beseech" , "More lip (anag)" .)
