I am unfortunately returning this Italian banger (6)
I believe the answer is:
salami
'italian banger' is the definition.
'salami' can be an answer for 'banger' (I've seen this before). I am not certain of the 'italian' bit.
'i am unfortunately returning' is the wordplay.
'i am' becomes 'I'm' (contraction).
'unfortunately' becomes 'alas' ('alas' is used to express regret).
'returning' says the letters should be written in reverse.
'im'+'alas'='imalas'
'imalas' in reverse letter order is 'SALAMI'.
'this' acts as a link.
Can you help me to learn more?
(Other definitions for salami that I've seen before include "Slim, graceful" , "Highly-seasonal sausage" , "Highly-seasoned Italian sausage" , "Cured meat" , "meat product" .)
