Cut of meat for Cliff in post? (5,3)
I believe the answer is:
scrag end
'cut of meat' is the definition.
(scrag end is a kind of cut of meat)
'cliff in post?' is the wordplay.
'cliff' becomes 'crag' (crag is a kind of cliff).
'in' means one lot of letters goes inside another.
'post?' becomes 'send' ('send' can be a synonym of 'post'**).
'crag' placed into 'send' is 'SCRAG-END'.
'for' is the link.
(Other definitions for scrag end that I've seen before include "cut of lamb" , "Inferior mutton" , "Meat" , "Lean piece of veal or mutton" , "Cut inferior" .)
