Relating to office work (8)
I believe the answer is:
clerical
'relating to office work' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for clerical that I've seen before include "Like error on paper" , "Office work; of the clergy" , "Such a collar" , "Relating to the priesthood or office work" , "working in an office" .)
