I believe the answer is:

<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">spring over</span>' is the definition.<br/ ><span class="explanation-format__explanation">(to vault something is to jump over it)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for vault that I've seen before include "Secure room in bank" , "Leap - wine or money chamber?" , "Leap - arched ceiling" , "You can do this with a pole" , "Jump over a crypt? (5)" .)
