Outfit without basis to work on a newspaper? (7)
I believe the answer is:
subedit
'work on a newspaper?' is the definition.
(I've seen this before)
'outfit without basis' is the wordplay.
'outfit' becomes 'suit' (suit is a type of outfit).
'without' means one lot of letters goes inside another ('without' can be similar in meaning to 'outside').
'basis' becomes 'bed' (bed can mean a basis or foundation).
'suit' placed around 'bed' is 'SUBEDIT'.
'to' is the link.
(Other definitions for subedit that I've seen before include "daily duty?" , "Work on story" , "Change and correct (printed material)" , "Work for daily" , "Work on paper" .)
