Chart-topping song has Eno making a comeback (6,3)
I believe the answer is:
number one
'chart-topping song has eno making a comeback' is the definition.
I can't tell whether this defines the answer.
'song has eno making a comeback' is the wordplay.
'song' becomes 'number' (I've seen this before**).
'has' means one lot of letters go next to another.
'making a comeback' shows that the letters should be reversed in order.
'eno' reversed gives 'one'.
'number'+'one'='NUMBER ONE'
Can you help me to learn more?
(Other definitions for number one that I've seen before include "Wee" , "the most important person" , "Musical success" , "Top-of-the-charts hit" , "arch" .)
