Firebrand puts key for me in Rolls-Royce (8)
I believe the answer is:
reformer
'firebrand' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'key for me in rolls-royce' is the wordplay.
'key' becomes 'e' (musical key).
'in' is an insertion indicator.
'rolls royce' becomes 'rr' (short for Rolls Royce).
'e'+'for'+'me'='eforme'
'eforme' placed inside 'rr' is 'REFORMER'.
'puts' acts as a link.
Can you help me to learn more?
(Other definitions for reformer that I've seen before include "One changing for the better" , "eg Luther" , "Person who advocates change" , "One who changes organisation in order to improve" , "Luther, perhaps" .)
