Authentic, detailed information interrupting restoration (7)
I believe the answer is:
renewal
'restoration' is the definition.
(synonyms)
'authentic detailed information interrupting' is the wordplay.
'authentic' becomes 'real' (I've seen this before).
'detailed information' becomes 'new' (I am not sure about this - if you are sure you should believe this answer much more).
'interrupting' is an insertion indicator.
'real' enclosing 'new' is 'RENEWAL'.
Can you help me to learn more?
(Other definitions for renewal that I've seen before include "Renovation; resumption" , "Rehabilitation" , "Replacement" , "Reinvigoration" , "modernisation?" .)
