'spiritual quack' is the definition.
The definition and answer can be both people as well as being singular nouns.
Perhaps they are linked in a way I don't understand?

'fake a new' is the wordplay.
'fake' becomes 'sham' (sham can mean fake or pretend).
'new' becomes 'n' (abbreviation as in New Testament NT).
'sham'+'a'+'n'='SHAMAN'

Can you help me to learn more?

(Other definitions for shaman that I've seen before include "who practises a form of spiritualism?" , "Spirit guide" , "Asian medicine man" , "16 21 [INDIAN IMPORT]" , "Witch doctor" .)
