Placed an amount on a piece of fruit (7)
I believe the answer is:
satsuma
'piece of fruit' is the definition.
'satsuma' can be an answer for 'fruit' (satsuma is a kind of fruit). I am not sure about the 'piece of' bit.
'placed an amount on a' is the wordplay.
'placed' becomes 'sat' (sitting is a kind of placing).
'an amount' becomes 'sum' (synonyms).
'on' means one lot of letters go next to another.
'sat'+'sum'+'a'='SATSUMA'
Can you help me to learn more?
(Other definitions for satsuma that I've seen before include "Orange - type of pottery" , "Small, easily-peeled orange" , "Kind of mandarin orange" , "Easily peeled orange" , "Seedless citrus fruit" .)
