Like filling tripe and grouse cut on a Sunday? (5,4)
I believe the answer is:
roast beef
'cut on a sunday?' is the definition.
'roast beef' can be an answer for 'cut' (roast beef is a kind of cut). I'm not sure about the 'on a sunday?' bit.
'like filling tripe and grouse' is the wordplay.
'like' becomes 'as'.
'filling' indicates putting letters inside.
'tripe' becomes 'rot' (I've seen this in another clue).
'and' is a charade indicator (letters next to each other).
'grouse' becomes 'beef' (synonyms).
'as' placed within 'rot' is 'roast'.
'roast'+'beef'='ROAST-BEEF'
Can you help me to learn more?
(Other definitions for roast beef that I've seen before include "Joint" , "Typical English dish" , "Typically 7 down dish" , "Traditional English food" , "meat dish" .)
