Journalist, heading away from hut (4)
I believe the answer is:
hack
'journalist' is the definition.
(hack can informally mean a journalist)
'heading away from hut' is the wordplay.
'heading away from' means to remove the first letter.
'hut' becomes 'shack' (synonyms).
'shack' with its initial letter taken off is 'HACK'.
(Other definitions for hack that I've seen before include "Cut roughly - routine writer" , "Writer of uninspiring stuff" , "Wildly kick; dull writer" , "Cut crudely - journalist" , "get information illegally" .)
