Cash contribution to education (5)
I believe the answer is:
ducat
'cash' is the definition.
The definition and answer can be both related to property as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'contribution to education' is the wordplay.
'contribution to' says the answer is hidden in the clue.
'DUCAT' is hidden in the letters of 'education'.
Can you help me to learn more?
(Other definitions for ducat that I've seen before include "Cut Da out an old coin" , "Ancient coin" , "Former European gold coin" , "Old Italian coin" , "Formerly a gold coin of several European countries" .)
