Wait where the cargo goes (4)
I believe the answer is:
hold
'wait' is the definition.
(synonyms)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for hold that I've seen before include "Clasp" , "Grasp; clutch" , "Cargo area of ship" , "Have or possess" , "Ship's cargo area" .)
