Complete opportunity to disregard children, it's said (9)
I believe the answer is:
utterance
'disregard children it's said' is the definition.
I can't tell whether this defines the answer.
'complete opportunity' is the wordplay.
'complete' becomes 'utter' (I've seen this before).
'opportunity' becomes 'ance' (I can't justify this - if you can you should give a lot more credence to this answer).
'utter'+'ance'='UTTERANCE'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for utterance that I've seen before include "one's said" , "sermon, say" , "Remark" , "Statement" , "Vocal expression" .)
