Some costal kibbutz gossip (4)
I believe the answer is:
talk
'gossip' is the definition.
(talk is a kind of gossip)
'some costal kibbutz' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'TALK' is hidden in the letters of 'costal kibbutz'.
(Other definitions for talk that I've seen before include "Gossip - lecture" , "See 10" , "Rabbit" , "Chatter" , "Chat" .)
