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