Fetch out an article for exposing (6)
I believe the answer is:
baring
'exposing' is the definition.
(baring is a kind of exposing)
'fetch out an article' is the wordplay.
'fetch' becomes 'bring' ('bring' can be a synonym of 'fetch').
'out' means one lot of letters goes inside another.
'an article' becomes 'a' (indefinite article).
'bring' placed around 'a' is 'BARING'.
'for' is the link.
(Other definitions for baring that I've seen before include "Exposing" , "Stripping or uncovering" .)
