Looks at ring again as an awful sight (7)
I believe the answer is:
eyesore
'an awful sight' is the definition.
'eyesore' can be an answer for 'sight' (eyesore can mean a horrible sight). I'm unsure of the 'an awful' bit.
'looks at ring again' is the wordplay.
'looks at' becomes 'eyes' (I've seen this before).
'ring' becomes 'O' (O is the shape of a ring).
'again' becomes 're' (prefix meaning 'again').
'eyes'+'o'+'re'='EYESORE'
'as' acts as a link.
Can you help me to learn more?
(Other definitions for eyesore that I've seen before include "Something ugly and offensive" , "Hideous building" , "Blemish" , "bad sight" , "Something exceedingly ugly" .)
