Crier out for the ruination of Rizzio, say (8)
I believe the answer is:
courtier
'say' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'crier out for the ruination of rizzio' is the wordplay.
'crier out' can be anagrammed to 'COURTIER'.
However, I'm not sure how the anagram is indicated.
Can you help me to learn more?
(Other definitions for courtier that I've seen before include "Sovereign's attendant" , "Attendant at palace" , "Setter" , "Palace hanger-on" , "Monarch's companion" .)
