Quiet, however (5)
I believe the answer is:
still
I believe this is a double definition.
'quiet' is the first definition.
(I know that quiet can be written as still)
'however' is the second definition.
(I know that however can be written as still)
(Other definitions for still that I've seen before include "Even now; not moving" , "Motionless, inactive" , "activity of one manufacturing spirits?" , "Stop" , "source of spirits" .)
