Pain-relieving; inoffensive (7)
I believe the answer is:
anodyne
I believe this clue is a double definition.
'pain-relieving' is the first definition.
(I've seen this before)
'inoffensive' is the second definition.
(I've seen this in another clue)
(Other definitions for anodyne that I've seen before include "Harmless, bland" , "Painkilling (medicine)" , "Inoffensive, rather dull" , "Easing pain and distress - annoyed (anag)" , "Soothing to the mind or feelings" .)
