Joint point (4)
I believe the answer is:
node
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">joint point</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 node that I've seen before include "Knob or lump" , "Where network lines meet" , "Burl" , "Where conductors meet" , "Done (anag.); a knot" .)
