<span class="explanation-format__ClueExplanation">This clue is a double definition.<br/ ><br/ >'<span class="explanation-format__original">seize</span>' is the first definition.<br/ ><span class="explanation-format__explanation">(I know that seize is a more specific form of the action hook)</span><br/ ><br/ >'<span class="explanation-format__original">entrap</span>' is the second definition.<br/ ><span class="explanation-format__explanation">(thesaurus)</span><br/ ><br/ ></span>
(Other definitions for catch that I've seen before include "Desirable husband; unforeseen problem" , "Grab; disadvantage" , "Fly in the ointment" , "secure" , "Understand" .)
