Network connection (4)
I believe the answer is:
node
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">network connection</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 node that I've seen before include "Intersection in a network" , "Point of branching in a network" , "Point at which several lines come together" , "Point of intersection" , "Point in network where lines intersect or branch" .)
