Lamb too frisky for lottery at fete (7)
I believe the answer is:
tombola
'lottery at fete' is the definition.
(lottery at a church fete)
'lamb too frisky' is the wordplay.
'frisky' indicates anagramming the letters.
'lamb'+'too'='lambtoo'
'lambtoo' anagrammed gives 'TOMBOLA'.
'for' acts as a link.
(Other definitions for tombola that I've seen before include "Fete game" , "Game played at fetes" , "Form of lottery" , "Small lottery at fete" , "Lottery in which tickets are drawn from a revolving drum" .)
