Utter, stark (5)
I believe the answer is:
sheer
I believe this clue is a double definition.
'utter' is the first definition.
(synonyms)
'stark' is the second definition.
(synonyms)
(Other definitions for sheer that I've seen before include "transparent fabric" , "avoid an unpleasant thing" , "Downright - deviation" , "total" , "Unqualified" .)
