Leg artery (5)
I believe the answer is:
iliac
'leg artery' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for iliac that I've seen before include "Like certain body parts" , "bottom of a hip bone" , "Relating to part of the hip bone" , "Pertaining to hip bone" , "Trojan" .)
