Water in a tureen (3)
I believe the answer is:
ure
'water' is the definition.
I know nothing about this answer so I can't judge whether this works.
'in a tureen' is the wordplay.
'in' indicates a hidden word.
'URE' is hidden in the letters of 'tureen'.
Can you help me to learn more?
(Other definitions for ure that I've seen before include "Midge --, singer" , "River at Ripon" , "Wensleydale river" , "River of N. Yorkshire" , "Ripon's river" .)
