Still in container terminal (5)
I believe the answer is:
inert
'still' is the definition.
(I've seen this before)
'in container terminal' is the wordplay.
'in' indicates the answer is hidden within the clue.
'INERT' is hidden within 'container terminal'.
(Other definitions for inert that I've seen before include "lacking energy" , "like nitrogen" , "Chemically inactive" , "Lifeless, without power to move or act" , "Not chemically active" .)
