Meadows in a rush to be set free
I believe the answer is:
released
'be set free' is the definition.
(I've seen this before)
'meadows in a rush' is the wordplay.
'meadows' becomes 'leas' (I've seen this before).
'in' is an insertion indicator.
'a rush' becomes 'reed' (I've seen this before).
'leas' inserted into 'reed' is 'RELEASED'.
'to' is the link.
(Other definitions for released that I've seen before include "Set free" , "Sent from prison" , "free after imprisonment?" , "Discharged" , "Liberated" .)
