Royal Shakespeare character in October only (6)
I believe the answer is:
oberon
'royal shakespeare character' is the definition.
The definition suggests a singular noun which matches the answer.
'in october only' is the wordplay.
'in' says the answer is hidden in the clue.
'OBERON' is hidden in the letters of 'october only'.
Can you help me to learn more?
(Other definitions for oberon that I've seen before include "Borneo (anag)" , "Fairy king (AMND)" , "Shakespearean role" , "top charmer!" , "King of the fairies, husband of Titania" .)
