Try to utter report (7)
I believe the answer is:
hearsay
'report' is the definition.
(I know that hearsay is a type of comment)
'try to utter' is the wordplay.
'try' becomes 'hear' (as in to try someone in court or hear their case).
'to utter' becomes 'say' (to utter something is to speak or say it).
'hear'+'say'='HEARSAY'
(Other definitions for hearsay that I've seen before include "rumoured" , "speculation" , "Gossip or rumour - not allowed as evidence" , "Gossip or idle talk - it's not evidence" , "Testimony not based on direct knowledge" .)
