Meadows covered in grass given up (8)
I believe the answer is:
released
'given up' is the definition.
('release' can be a synonym of 'give up')
'meadows covered in grass' is the wordplay.
'meadows' becomes 'leas' (I've seen this before).
'covered in' indicates putting letters inside.
'grass' becomes 'reed' (I've seen this before).
'leas' inserted into 'reed' is 'RELEASED'.
(Other definitions for released that I've seen before include "Liberated" , "Sent from prison" , "Set free" , "Discharged" , "Freed from confinement" .)
