Of the wrist (6)
I believe the answer is:
carpal
'of the wrist' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for carpal that I've seen before include "Wrist bone" , "regarding part of the lower arm" , "Type of tunnel producing complaint" , "Wrist-bone" , "Of the wrist bones" .)
