Ugly sight I noticed, reportedly (7)
I believe the answer is:
eyesore
'ugly sight' is the definition.
(eyesore can mean something horrible to look at)
'i noticed reportedly' is the wordplay.
'i' becomes 'eye' (I've seen this in other clues).
'noticed' becomes 'saw' (I've seen this in another clue).
'reportedly' indicates a 'sounds like' (homophone) clue.
'saw' sounds like 'sore'.
'eye'+'sore'='EYESORE'
(Other definitions for eyesore that I've seen before include "Blot on the landscape" , "Ugly and offensive sight" , "Something that's ugly" , "Ugly structure" , "Blight" .)
