Witchdoctor's fake article (6)

I believe the answer is:

shaman

I'm a little stuck... Click here to teach me more about this clue!

'witchdoctor's' is the definition.
I can't tell whether this definition defines the answer.

'fake article' is the wordplay.
'fake' becomes 'sham' (sham can mean fake or pretend).
'article' becomes 'an' (indefinite article).
'sham'+'an'='SHAMAN'

Can you help me to learn more?

(Other definitions for shaman that I've seen before include "16 21 [INDIAN IMPORT]" , "Doctor-priest working by magic" , "Witch doctor" , "Man of spirit" , "Medium between the visible and spirit worlds" .)

I've seen this clue in The Independent.
