Trampled in an endless rush (7)
I believe the answer is:
stamped
'trampled' is the definition.
(I've seen this before)
'an endless rush' is the wordplay.
'an endless' means to remove the last letter.
'rush' becomes 'stampede' (I've seen this before).
'stampede' with its final letter taken off is 'STAMPED'.
'in' is the link.
(Other definitions for stamped that I've seen before include "Impressed" , "Brought the foot down loudly" , "made an impression" , "trampled" , "Walked noisily or angrily" .)
