One spouted, always inhibiting wife (4)
I believe the answer is:
ewer
'one spouted' is the definition.
(something with a spout)
'always inhibiting wife' is the wordplay.
'always' becomes 'eer' (poetic way of saying ever).
'inhibiting' is an insertion indicator.
'wife' becomes 'w'.
'eer' placed around 'w' is 'EWER'.
(Other definitions for ewer that I've seen before include "Oversized jug" , "A wide-mouthed water jug" , "Jug with wide spout" , "water-carrier" , "29 [VESSEL]" .)
