Gossip, hearsay (6)
I believe the answer is:
rumour
I believe this is a double definition.
'gossip' is the first definition.
(rumouring is a kind of gossiping)
'hearsay' is the second definition.
(synonyms)
(Other definitions for rumour that I've seen before include "Doubtful story" , "Report of doubtful truth" , "Story going around" , "buzz" , "Hearsay, gossip" .)
