Large vessel with handle and spout (6)
I believe the answer is:
flagon
'large vessel with handle and spout' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for flagon that I've seen before include "Large rounded bottle for cider or wine" , "Large vessel for beverages" , "Large container for serving drink" , "Large round bottle as for cider" , "Snow White companion" .)
