<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">stableman at an inn</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for ostler that I've seen before include "Nags for me" , "Groom, stableman" , "Inn servant" , "Horse attendant" , "Attendant for horses in olden times" .)
