Low joint where members meet (5)
I believe the answer is:
ankle
'low joint' is the definition.
(I've seen this in another clue)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for ankle that I've seen before include "Part of the leg between the foot and the shin" , "Narrow part of leg" , "Joint between foot and leg" , "Location of the talus" , "Major foot joint" .)
