I hear you are opening six water jugs (5)
I believe the answer is:
ewers
'water jugs' is the definition.
(I've seen this in another clue)
'i hear you are opening six' is the wordplay.
'i hear' indicates a 'sounds like' (homophone) clue.
'are opening six' becomes 'rs' (I am not sure about this - if you are sure you should believe this answer much more).
'you' is a homophone of 'ewe'.
'ewe'+'rs'='EWERS'
Can you help me to learn more?
(Other definitions for ewers that I've seen before include "Water jugs" , "Vase-shaped jugs" , "Pitchers" , "Large jugs" , "Vessels with handle and spout" .)
