Put back concerning chapter in correction for legally true statement (13)
I believe the answer is:
certification
'legally true statement' is the definition.
The answer and definition can be both related to communication as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'put back concerning chapter in correction' is the wordplay.
I cannot quite understand how this works, but
'concerning' could be 'on' (both can mean 'in relation to') and 'on' is found within the answer.
'chapter' could be 'c' (abbreviation) and 'c' is found within the answer.
This explanation may well be incorrect...
'for' acts as a link.
Can you help me to learn more?
(Other definitions for certification that I've seen before include "legal document!" , "Process of allocating film ratings" .)
