Sleeve part (4)
I believe the answer is:
cuff
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">sleeve part</span>' is the definition.<br/ ><span class="explanation-format__explanation">('cuff' is part of 'sleeve')</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for cuff that I've seen before include "Smack; end of shirt sleeve" , "Blow; end of sleeve" , "Blow - on the wrist?" , "Smack; Moonstone sergeant" , "minor assault" .)
