Laid down law: raid done badly (8)
I believe the answer is:
ordained
'laid down law' is the definition.
Although both the answer and definition are past participle verbs, I cannot understand how they can define each other.
'raid done badly' is the wordplay.
'badly' indicates an anagram.
'raid'+'done'='raiddone'
'raiddone' is an anagram of 'ORDAINED'.
Can you help me to learn more?
(Other definitions for ordained that I've seen before include "Appointed to a clerical post" , "Laid down the law" , "Elevated to the priesthood" , "Like a priest" , "Decreed, or appointed to priesthood" .)
