Fringes of occult in general to do with signs or symbols (10)
I believe the answer is:
notational
'fringes of occult' is the definition.
The definition suggests an adjective which matches the answer.
I don't understand the remainder of the clue.
Can you help me to learn more?
(Another definition for notational that I've seen is " about special symbols".)
I've seen this clue in The Times and The Sunday Times.
Want a hint initially instead of a full solution?
