Vagrant was in front getting trodden on (8)
I believe the answer is:
trampled
'trodden on' is the definition.
'trampled' can be an answer for 'trodden' ('trample' can be a synonym of 'tread'). I'm unsure of the 'on' bit.
'vagrant was in front getting' is the wordplay.
'vagrant' becomes 'tramp' (I've seen this before).
'was in front' becomes 'led' (I've seen this in another clue).
'getting' says to put letters next to each other.
'tramp'+'led'='TRAMPLED'
Can you help me to learn more?
(Other definitions for trampled that I've seen before include "Trodden underfoot" , "crushed" , "Walked heavily or roughly" , "Trod roughly underfoot" .)
