<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">go about stealthily</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for prowl that I've seen before include "Move about with unlawful intentions" , "Go stealthily, as if searching" , "Move stealthily around" , "Roam in search of prey" , "Slink after prey" .)
