<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">like an uncle</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 avuncular that I've seen before include "Genial" , "Kind and indulgent" , "Of an uncle - friendly" , "Like a kindly uncle" , "Kind and friendly towards a younger or less experienced person" .)
