<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">horse breed</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for arab that I've seen before include "Horse of a breed originating in the Middle East" , "Saudi or Omani, perhaps" , "Saudi, e.g." , "Saudi, perhaps - breed of horse" , "Qatari or Omani, say" .)
