Got off (4)
I believe the answer is:
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">got off</span>' is the definition.<br/ ><span class="explanation-format__explanation">('alight' can mean to get off a vehicle)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for alit that I've seen before include "Settled" , "got off" , "Landed" , "Climbed down from" , "Came down to earth" .)
