Spirit behind someone else's work? (5,6)
I believe the answer is:
ghost writer
'else's work?' is the definition.
I can't judge whether this definition defines the answer.
'spirit behind someone' is the wordplay.
'spirit' becomes 'ghost' (ghost is a kind of spirit).
'behind someone' becomes 'writer' (writer is a kind of someone. I am not sure about the 'behind' bit.**).
'ghost'+'writer'='GHOST-WRITER'
Can you help me to learn more?
(Other definitions for ghost writer that I've seen before include "Author working for another" , "Person writing for another who takes the credit" , "Not the credited author" , "Uncredited author" , "One producing book in another's name" .)
