A tramp (4)
I believe the answer is:
hobo
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">a tramp</span>' is the definition.<br/ ><span class="explanation-format__explanation">(both can mean a homeless person)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for hobo that I've seen before include "Vagrant (US)" , "Bum" , "Vagrant (American)" , "Vagrant, tramp" , "Homeless American" .)
