I believe the answer is:
dense
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">compacted</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 dense that I've seen before include "Closely-spaced" , "Thick and tightly-packed" , "Heavy" , "Thick, compact or crowded" , "Thick; stupid" .)
