Role man arranged as a charity worker (7)
I believe the answer is:
almoner
'a charity worker' is the definition.
(I've seen this before)
'role man arranged' is the wordplay.
'arranged' indicates anagramming the letters.
'role'+'man'='roleman'
'roleman' anagrammed gives 'ALMONER'.
'as' is the link.
(Other definitions for almoner that I've seen before include "welfare worker once" , "Charity worker" , "Hospital social worker" , "Man role (anag.)" , "Medical social worker in earlier times" .)
