Guide animal from herd (5)
I believe the answer is:
steer
I believe this is a triple definition!
'guide' is the first definition.
(I know that guide can be written as steer)
'animal' is the second definition.
(I've seen this before)
'from' is a link.
'herd' is the third definition.
(I've seen this before)
(Other definitions for steer that I've seen before include "Direct, fix course" , "Guide, control" , "bovine individual?" , "Manoeuvre" , "Cattle - guide" .)
