Nozzle (5)
I believe the answer is:
spout
'nozzle' is the definition.
(I know that nozzle can be written as spout)
This is the entire clue.
(Other definitions for spout that I've seen before include "Discharge" , "Teapot pourer" , "Speak in a declamatory way; pipe for liquid" , "Pouts beneath jet of liquid" , "Mouth of a kettle" .)
