The meadow beyond the river (7)
I believe the answer is:
pasture
'the meadow' is the definition.
(I've seen this before)
'beyond the river' is the wordplay.
'beyond' becomes 'past' (to go beyond something is to go past it).
'the river' becomes 'ure' (River Ure).
'past'+'ure'='PASTURE'
(Other definitions for pasture that I've seen before include "Land suitable for grazing" , "Land for grazing cattle" , "Meadowland" , "Field suitable for grazing" , "Stock holder, perhaps" .)
