I'm a little stuck... Click here to teach me more about this clue!

'tory' is the definition.
Both the definition and answer are singular nouns.
Maybe they are linked in a way I don't understand?

I don't understand the rest of the clue.

Can you help me to learn more?

(Other definitions for enoch that I've seen before include "Man in Bible" , "Oldest city father" , "OT patriarch" , "___ Powell, Tory politician, d. 1998" , "Son of murderer" .)

I've seen this clue in The Independent.
