I believe the answer is:
wrist
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">carpus</span>' is the definition.<br/ ><span class="explanation-format__explanation">(synonyms)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for wrist that I've seen before include "Where to keep watch" , "Hand/arm joint" , "Type of 1 ac" , "Joint (the carpus)" , "Arm to hand connection, the carpus" .)
