Doctor-priest not genuine article (6)
I believe the answer is:
shaman
'doctor-priest' is the definition.
(I've seen this before)
'not genuine article' is the wordplay.
'not genuine' becomes 'sham' (I've seen this in another clue).
'article' becomes 'an' (indefinite article).
'sham'+'an'='SHAMAN'
(Other definitions for shaman that I've seen before include "Indian priest" , "Doctor-priest working by magic" , "16 21 [INDIAN IMPORT]" , "Asian medicine man" , "Asian doctor-priest" .)
