Partly cover (7)
I believe the answer is:
overlap
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">partly cover</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for overlap that I've seen before include "Ride" , "bit of a coincidence" , "Coincide in part" , "Rest one on another" , "Lie partly on top of" .)
