Faucet drip (4)
I believe the answer is:
leak
'faucet drip' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for leak that I've seen before include "Accidental hole allowing liquid to escape" , "Secrecy breach" , "Liquid loss sounds like a vegetable" , "Intentional release of secrets" , "Disclose (secrets)" .)
