Worker on newspaper throws debris out (9)
I believe the answer is:
subeditor
'worker on newspaper' is the definition.
'subeditor' can be an answer for 'worker' (subeditor is a kind of worker). I am not certain of the 'on newspaper' bit.
'throws debris out' is the wordplay.
'throws' indicates an anagram.
'debris'+'out'='debrisout'
'debrisout' with letters rearranged gives 'SUBEDITOR'.
Can you help me to learn more?
(Other definitions for subeditor that I've seen before include "Newspaper worker" , "journalist" , "Observer employee?" , "Employee on paper" , "Newspaper employee" .)
