Give money to teachers for pastry (8)
I believe the answer is:
doughnut
'pastry' is the definition.
The answer and definition can be both things that one consumes for nourishment as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
'give money to teachers' is the wordplay.
'give' means one lot of letters go next to another.
'money' becomes 'dough' (dough can informally mean money).
'to teachers' becomes 'nut' (National Union of Teachers).
'dough'+'nut' is 'DOUGHNUT'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for doughnut that I've seen before include "Small ring-shaped fried cake" , "Jam-filled cake" , "Sweet cookie" , "Small tasty cake with hole in middle" , "Sweet circular cake" .)
