Leading from the bend (4)
I believe the answer is:
arch
This clue is a double definition.
'leading' is the first definition.
(e.g. in arch-enemy)
'the bend' is the second definition.
(thesaurus)
'from' is the link.
(Other definitions for arch that I've seen before include "Curve of the foot" , "not to go straight?" , "a piece about a foot?" , "Char the curved structure" , "Affectedly playful like curved structure" .)
