Steal away (5)
I believe the answer is:
elope
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">steal away</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for elope that I've seen before include "run off with another?" , "escape" , "Run away with lover" , "Run away with one's beloved" , "do a moonlight flit" .)
