Moose held back by six-footer with chain (6)
I believe the answer is:
anklet
'chain' is the definition.
(I've seen this before)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for anklet that I've seen before include "joint protector" , "Fetter" , "Leg decoration" , "Ornament for lower leg" , "Jewellery worn around the bottom of the leg" .)
