Still stored in container terminal (5)
I believe the answer is:
inert
'still' is the definition.
(not moving)
'stored in container terminal' is the wordplay.
'stored 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 "Sluggish, still" , "Chemically inactive" , "lazy" , "Motionless or inanimate" , "'Not moving, lifeless (5)'" .)
