<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">young fellow</span>' is the definition.<br/ ><span class="explanation-format__explanation">(lad can mean a young boy)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for lad that I've seen before include "Son" , "Boy or youth" , "(Housman's Shropshire) boy" , "Scottish lover" , "Chap, fellow" .)
