Nevertheless, still (3)
I believe the answer is:
but
I believe this is a double definition.
'nevertheless' is the first definition.
(I've seen this before)
'still' is the second definition.
(I've seen this in other clues)
(Other definitions for but that I've seen before include "Only; apart from" , "SECOND PART OF 10" , "Only in attribution" , "Save" , "Nevertheless, on the other hand" .)
