Even dull writers deliver some kicks (5)
I believe the answer is:
hacks
'even dull writers' is the definition.
'hacks' can be an answer for 'writers' (hack is a kind of writer). I'm not sure about the 'even dull' bit.
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for hacks that I've seen before include "Coughs" , "Cuts roughly; bad writers" , "Shack up with lowly journalists" , "kicks on the shin" , "Nags" .)
