Trampled, with "on" (4)
I believe the answer is:
trod
'trampled with on' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for trod that I've seen before include "start making wine" , "Trampled" , "Walked heavily, put foot down" , "Took steps" , "Trudged, stepped" .)
