Eminent person putting currency in - good heavens (7)
I believe the answer is:
grandee
'eminent person' is the definition.
(I've seen this before)
'currency in good heavens' is the wordplay.
'currency' becomes 'rand' (I've seen this before).
'in' means one lot of letters goes inside another.
'good heavens' becomes 'gee' (I can't explain this - if you can you should give a lot more credence to this answer).
'rand' put inside 'gee' is 'GRANDEE'.
'putting' acts as a link.
Can you help me to learn more?
(Other definitions for grandee that I've seen before include "European lord" , "aristocrat" , "Person of eminence" , "One of high rank" , "Person of high rank" .)
