Rubbish article I'm leaving (2-2)
I believe the answer is:
ta-ta
'i'm leaving' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.
'rubbish article' is the wordplay.
'rubbish' becomes 'tat' (low-quality items or material).
'article' becomes 'a' (the indefinite article in English).
'tat'+'a'='TA-TA'
Can you help me to learn more?
(Other definitions for ta-ta that I've seen before include "Adieu" , "Cheerio" , "Bye-bye" , "Bye!" , "A Farewell" .)
