Nevertheless, calm (5)
I believe the answer is:
still
This clue is a double definition.
'nevertheless' is the first definition.
(I know that nevertheless can be written as still)
'calm' is the second definition.
(I know that calm can be written as still)
(Other definitions for still that I've seen before include "... [STRONG LIQUOR] produced by this" , "source of spirits" , "Motionless - nevertheless" , "subdued" , "in spite of this" .)
