Being very close, he may move to Reims (5)
I believe the answer is:
miser
'being' is the definition.
(miser is a kind of being)
'close he may move to reims' is the wordplay.
'reims' can be anagrammed to 'MISER'.
But, I'm unsure how this is indicated.
'very' is the link.
Can you help me to learn more?
(Other definitions for miser that I've seen before include "Wealth hoarder" , "Stingy type" , "One of the people who spend least" , "not a spendthrift" , "Penny-pincher" .)
