Buff Scandinavian coins found round church (5)
I believe the answer is:
ochre
'buff' is the definition.
(I've seen this before)
'scandinavian coins found round church' is the wordplay.
'scandinavian coins' becomes 'ore' (I have seen 'Small coins' mean 'ore' so perhaps 'coins' could also mean 'ore'. I am not sure about the 'scandinavian' bit.).
'found round' indicates putting letters inside.
'church' becomes 'ch' (common abbreviation).
'ore' enclosing 'ch' is 'OCHRE'.
Can you help me to learn more?
(Other definitions for ochre that I've seen before include "Brown" , "Pale brownish-yellow colour or pigment" , "Chore using pale brownish colour (5)" , "An orangey pigment" , "natural colouring" .)
