<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">young boy</span>' is the definition.<br/ ><span class="explanation-format__explanation">(lad can mean a boy or young man)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for lad that I've seen before include "Shaver" , "Young fellow" , "Stable worker" , "Boy, young man" , "Son" .)
