Note sections of family into baroque restoration (12)
I believe the answer is:
regeneration
'restoration' is the definition.
(thesaurus)
'note sections of family into baroque' is the wordplay.
'note' becomes 're' (as in do-re-mi).
'sections of family' becomes 'genera' (I can't justify this - if you can you should believe this answer much more).
'baroque' is an anagram indicator (baroque can mean fancy or complex).
'into' with letters rearranged gives 'tion'.
're'+'genera'+'tion'='REGENERATION'
Can you help me to learn more?
(Other definitions for regeneration that I've seen before include "What Doctor Who undergoes periodically" , "Process of renewal" , "Character change for Doctor Who" , "Way to bring new life to an area" , "Process of bringing new life to an area" .)
