Talk about new renovations (12)
I believe the answer is:
conversation
'talk' is the definition.
(thesaurus)
'about new renovations' is the wordplay.
'about' becomes 'c' (abbreviation for 'circa'**).
'new' indicates anagramming the letters.
'renovations' is an anagram of 'onversation'.
'c'+'onversation'='CONVERSATION'
(Other definitions for conversation that I've seen before include "discussion" , "dialogue" , "Talk, chat" , "Something to talk about?" , "22 between people" .)
