<span class="explanation-format__ClueExplanation">I believe this is a double definition.<br/ ><br/ >'<span class="explanation-format__original">exceed</span>' is the first definition.<br/ ><span class="explanation-format__explanation">(I know that exceed can be written as pass)</span><br/ ><br/ >'<span class="explanation-format__original">mountain route</span>' is the second definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ ></span>
(Other definitions for pass that I've seen before include "Go by; succeed in (an exam)" , "Approve; mountain route" , "Overtake; mountain way" , "Authorise; overtake" , "Overtake; permit" .)
