Restoration of wild rye after cover is ploughed up (8)
I believe the answer is:
recovery
'restoration' is the definition.
(thesaurus)
'wild rye after cover is ploughed up' is the wordplay.
'wild' indicates anagramming the letters.
'after' says to put letters next to each other.
'is ploughed up' indicates an anagram.
'rye' is an anagram of 'ery'.
'cover' with letters rearranged gives 'recov'.
'ery' after 'recov' is 'RECOVERY'.
'of' acts as a link.
(Other definitions for recovery that I've seen before include "Act of getting better" , "A return to a normal state of health" , "Green shoots could be a sign of this" , "Salvage" , "Bringing home a brokendown vehicle" .)
