One spouted, always having to confine wife (4)
I believe the answer is:
ewer
'one spouted' is the definition.
(something with a spout)
'always having to confine wife' is the wordplay.
'always' becomes 'eer' (poetic way of saying ever).
'having' indicates putting letters inside.
'to confine wife' becomes 'w' (I can't explain this - if you can you should believe this answer much more).
'eer' placed around 'w' is 'EWER'.
Can you help me to learn more?
(Other definitions for ewer that I've seen before include "A type of jug" , "Sort of jug" , "Large pitcher" , "Water jug with wide mouth" , "Big jug" .)
