From one side to the other (6)
I believe the answer is:
across
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">from one side to the other</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for across that I've seen before include "Transversely" , "Astride" , "Clues like this" , "sort of clue?" , "From side to side of (something)" .)
