Meat roll in South Africa affected Liam (6)
I believe the answer is:
salami
'meat' is the definition.
(salami is a kind of meat)
'south africa affected liam' is the wordplay.
'south africa' becomes 'SA' (abbreviation).
'affected' is an anagram indicator.
'liam' with letters rearranged gives 'lami'.
'sa'+'lami'='SALAMI'
'roll in' acts as a link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for salami that I've seen before include "Sausage served sliced" , "Savoury snack" , "Banger" , "Highly spiced sausage" , "A highly seasoned type of sausage" .)
