Crossword component (4)
I believe the answer is:
grid
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">crossword component</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 grid that I've seen before include "Network of intersecting lines" , "Pattern of crossing lines" , "Map reference system" , "a network of squares as in this puzzle" , "crossword, but no clues" .)
