Looks at the ring again. It is ugly (7)
I believe the answer is:
eyesore
'it is ugly' is the definition.
The definition suggests a singular noun which matches the answer.
'looks at the ring again' is the wordplay.
'looks at' becomes 'eyes' (I've seen this before).
'the ring' becomes 'o'.
'again' becomes 're'.
'eyes'+'o'+'re'='EYESORE'
Can you help me to learn more?
(Other definitions for eyesore that I've seen before include "it looks bad" , "Blot on the landscape" , "ugly feature" , "Ugly and offensive sight" , "Horrible sight" .)
