Unlikely to cause offence (7)
I believe the answer is:
anodyne
'unlikely to cause offence' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for anodyne that I've seen before include "Easing pain and distress - annoyed (anag)" , "(Medicine) able to relieve pain" , "Soothing to the mind or feelings" , "Avoiding controversy - done any (anag)" , "Dully uncontroversial" .)
