Writer to get a kick out of? (4)
I believe the answer is:
hack
'writer' is the definition.
(hack can mean a journalist)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for hack that I've seen before include "Cut crudely - journalist" , "Journalistic drudge (for the chop?)" , "Ride" , "Wildly kick; dull writer" , "Chop at hired horse?" .)
