abut
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">lie next to</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for abut that I've seen before include "Adjoin, touch" , "Adjoin -- 19 (rev)" , "Lean against the odd tuba" , "Be next to -- share a boundary" , "Of building or land, end or lean against" .)
