The end of the steak? (4)
I believe the answer is:
rump
I believe this clue is a double definition.
'the end' is the first definition.
(thesaurus)
'steak?' is the second definition.
(rump steak is a kind of steak)
'of the' is the link.
(Other definitions for rump that I've seen before include "Meat (from behind?)" , "Seat" , "Rear; buttocks" , "Mammal's hind part" , "Unimportant remnant" .)
