Quiet yet? (5)
I believe the answer is:
still
I believe this is a double definition.
'quiet' is the first definition.
('still' can be a synonym of 'quiet')
'yet?' is the second definition.
('still' can be a synonym of 'yet')
(Other definitions for still that I've seen before include "... [STRONG LIQUOR] produced by this" , "Immobile" , "in spite of this" , "sort of life" , "Not going anywhere" .)
