Garbled orison from a 'Twelfth Night' character (6)
I believe the answer is:
orsino
'a twelfth night character' is the definition.
The definition suggests a singular noun which matches the answer.
'garbled orison' is the wordplay.
'garbled' is an anagram indicator.
'orison' is an anagram of 'ORSINO'.
'from' acts as a link.
Can you help me to learn more?
(Other definitions for orsino that I've seen before include "Shakespearean duke" , "Twelfth Night duke" , "A duke, European" , "Duke of Illyria" , "one in Twelfth Night" .)
