Motionless to this day (5)
I believe the answer is:
still
I believe this clue is a double definition.
'motionless' is the first definition.
(synonyms)
'to this day' is the second definition.
(I've seen this in another clue)
(Other definitions for still that I've seen before include "Motionless, not sparkling" , "subdued" , "Unmoving yet" , "gentle" , "Stationary" .)
