Pitcher in side we rated (4)
I believe the answer is:
ewer
'pitcher' is the definition.
('ewer' can be a synonym of 'pitcher')
'in side we rated' is the wordplay.
'in' says the answer is hidden in the clue.
'EWER' can be found hidden inside 'side we rated'.
(Other definitions for ewer that I've seen before include "Large water jug" , "Large, wide-mouthed jug" , "A wide-lipped jug" , "from which liquid may be poured" , "Decorative pitcher" .)
