Tittle-tattle (6)
I believe the answer is:
gossip
'tittle-tattle' is the definition.
(I know that tittle-tattle can be written as gossip)
This is all the clue.
(Other definitions for gossip that I've seen before include "Scandalous rumour" , "Malicious talk about other people" , "Schmooze" , "Idle and mildly malicious talk" , "Piece of news that may or may not be true" .)
