Walk like a vagabond (5)
I believe the answer is:
tramp
I believe this is a double definition.
'walk' is the first definition.
(tramp can mean to walk around)
'a vagabond' is the second definition.
(I know that tramp is a type of vagabond)
'like' acts as a link.
(Other definitions for tramp that I've seen before include "cargo boat" , "Vagrant, long walk" , "Footslog" , "I might hitch a lift" , "Tread heavily (on)" .)
