Word before "still" or "tight" (3)
I believe the answer is:
sit
'word before still or tight' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for sit that I've seen before include "Order dog to behave" , "Serve (on jury)" , "I sell badly the cotton yarn" , "(Of bird) stay on nest" , "Take weight off feet" .)
