Spat spot (5)
I believe the answer is:
ankle
'spat spot' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for ankle that I've seen before include "Major joint in lower limb" , "Joint between foot and leg" , "Part of the leg between the foot and the shin" , "Major foot joint" , "Narrow part of leg" .)
