Special study meal (6)
I believe the answer is:
spread
'meal' is the definition.
(thesaurus)
'special study' is the wordplay.
'special' becomes 'sp'.
'study' becomes 'read' ('read' can be a synonym of 'study').
'sp'+'read'='SPREAD'
(Other definitions for spread that I've seen before include "Extend -- feast" , "butter?" , "Broaden - drapes (anag)" , "Feature" , "Gradually reach a wider area" .)
