Article supports fake healer (6)
I believe the answer is:
shaman
'healer' is the definition.
(I know that shaman is a type of healer)
'article supports fake' is the wordplay.
'article' becomes 'an' (English indefinite article).
'supports' means one lot of letters go next to another (bottom letters provide a support for the top ones).
'fake' becomes 'sham' (sham can mean fake or pretend).
'an' put after 'sham' is 'SHAMAN'.
(Other definitions for shaman that I've seen before include "religious figure" , "Asian medicine man" , "Asian doctor-priest" , "Man of spirit" , "Spirit guide" .)
