For “pastry”, go to the next page (8)
I believe the answer is:
turnover
'for pastry' is the definition.
(turnover is a kind of pastry)
'go to the next page' is the wordplay.
'go' becomes 'turn' (as in one's go or turn in a game).
'to the next page' becomes 'over' (I can't explain this - if you can you should believe this answer much more).
'turn'+'over'='TURNOVER'
Can you help me to learn more?
(Other definitions for turnover that I've seen before include "Tart" , "sweet" , "sales of > pastry?" , "patisserie product" , "money handled by business" .)
