Unskilled writer (4)
I believe the answer is:
hack
'unskilled writer' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for hack that I've seen before include "Chop; uninspired writer" , "persistent cough" , "Put up with" , "Cut - literary drudge - work horse" , "try to access unauthorised data" .)
