Leg part a little lower? (4)
I believe the answer is:
calf
I believe this clue is a triple definition!
'leg' is the first definition.
(thesaurus)
'part' is the second definition.
(calf is a kind of part)
'a little lower?' is the third definition.
(I've seen this in another clue)
(Other definitions for calf that I've seen before include "Bovine youngster" , "Young cow/bull" , "stocking filler" , "new jumbo?" , "Animal that yields veal" .)
