Trap let loose produces gossip (7)
I believe the answer is:
prattle
'gossip' is the definition.
(thesaurus)
'trap let loose' is the wordplay.
'loose' indicates an anagram (letters are loosened from their original positions).
'trap'+'let'='traplet'
'traplet' with letters rearranged gives 'PRATTLE'.
'produces' acts as a link.
(Other definitions for prattle that I've seen before include "Childish talk" , "Foolish talk" , "Chatter inconsequentially, natter" , "Talk childishly" , "rabbit" .)
