Rumour, gossip (7)
I believe the answer is:
hearsay
I believe this clue is a double definition.
'rumour' is the first definition.
(synonyms)
'gossip' is the second definition.
(hearsay is a kind of gossip)
(Other definitions for hearsay that I've seen before include "Common talk" , "Gossip passed around by word of mouth" , "Based on report given by others" , "Testimony not based on direct knowledge" , "Gossip or idle talk - it's not evidence" .)
