Walks like vagrants (6)
I believe the answer is:
tramps
I believe this clue is a double definition.
'walks' is the first definition.
(tramp is a kind of walk)
'vagrants' is the second definition.
(I know this)
'like' acts as a link.
(Other definitions for tramps that I've seen before include "Stumps" , "Goes on a long walk" , "Become hard or solid" , "Hiking vagrants" , "Vagrants or hoboes" .)
