<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">land measures</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for acres that I've seen before include "Areas of 4840 square yards" , "One of them has 4840 square yards" , "large area of land" , "Imperial units or measures of land" , "fields?" .)
