Quarter of bushel on floor in imperial currency (6)
I believe the answer is:
kopeck
'quarter of bushel' is the definition.
The answer and definition can be both quantities as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'on floor in imperial currency' is the wordplay.
'on' means one lot of letters go next to another.
'floor' becomes 'ko' (I've seen this in other clues).
'in imperial currency' becomes 'peck' (I can't explain this - if you can you should believe this answer much more).
'ko' put next to 'peck' is 'KOPECK'.
Can you help me to learn more?
(Other definitions for kopeck that I've seen before include "One-hundredth of a rouble" , "little Russian money" , "One hundred of these make one rouble" , "Russian coin" , "Russian copper" .)
