<span class="explanation-format__ClueExplanation">I believe this is a double definition.<br/ ><br/ >'<span class="explanation-format__original">march</span>' is the first definition.<br/ ><span class="explanation-format__explanation">(tramping is a kind of marching)</span><br/ ><br/ >'<span class="explanation-format__original">vagrant</span>' is the second definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ ></span>
(Other definitions for tramp that I've seen before include "Lady or gentleman of the road or roving ship" , "Walk heavily, as when weary, or through mud" , "one unlikely ever to have a mortgage!" , "man down on his luck" , "Heavy footsteps" .)
