<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">tillable</span>' is the definition.<br/ ><span class="explanation-format__explanation">(synonyms)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for arable that I've seen before include "Productive" , "Such land is fit for tillage" , "agricultural land" , "(Of land) able to be cultivated" , "(Of land) capable of producing crops" .)
