A role to play in relief work? (5)
I believe the answer is:
cameo
This clue could be a double definition.
'a role' is the first definition.
(I have seen 'Brief role ' mean 'cameo' so perhaps 'role' could also mean 'cameo')
'relief work?' is the second definition.
(I've seen this in another clue)
'to play in' is the link.
I am not very happy about this link. Some or all of it may belong to one of the definitions.
Can you help me to learn more?
(Other definitions for cameo that I've seen before include "Jewellery item with carved portrait" , "Medallion with a profile carved in relief" , "Small piece of hard stone carved with raised design" , "Small acting role; item of jewellery" , "Piece of jewellery with carved portrait" .)
