I believe the answer is:
uncle
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">brother of a parent</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for uncle that I've seen before include "Sam, perhaps" , "one who's taken the pledge" , "Male relative - pawnbroker" , "takes the pledge" , "For example, Tom Cobbleigh" .)
