Walked over (4)
I believe the answer is:
trod
'walked over' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for trod that I've seen before include "Stepped heavily" , "Walked in a specific way" , "Walked upon" , "Crushed (grapes) by foot" , "Walked (on something)" .)
