Loquacious (6)
I believe the answer is:
chatty
'loquacious' is the definition.
(I know that loquacious can be written as chatty)
This is the entire clue.
(Other definitions for chatty that I've seen before include "Fond of talking" , "given to blethering" , "Talkative or garrulous" , "Full of (trivial) conversation" , "Communicative" .)
