An old tenor of faith leaving South Africa (6)
I believe the answer is:
caruso
'an old tenor' is the definition.
'caruso' can be an answer for 'tenor' (singer Enrico Caruso). I'm not sure about the 'an old' bit.
'of faith leaving south africa' is the wordplay.
'of' is an anagram indicator (the answer comes from or 'of' the letters).
'leaving' is a deletion indicator.
'south'+'africa'='southafrica'
'southafrica' with 'faith' removed is 'sourca'.
'sourca' with letters rearranged gives 'CARUSO'.
Can you help me to learn more?
(Other definitions for caruso that I've seen before include "songster" , "Enrico ...... was famous Italian tenor" , "Opera singer" , "Enrico ......, late great Italian tenor" , "Enrico -, twentieth century Italian tenor" .)
