End of novel this writer’s not previously recorded (4)
I believe the answer is:
live
'not previously recorded' is the definition.
The answer and definition are not the same part of speech. However, adjectives and past participle verbs occasionally define each other.
'end of novel this writer's' is the wordplay.
'end of' says to take the final letters.
'this writer's' becomes 'ive' ('I have' can refer to the person writing).
The final letter of 'novel' is 'l'.
'l'+'ive'='LIVE'
Can you help me to learn more?
(Other definitions for live that I've seen before include "Of TV programme, seen while taking place" , "A . . . . wire is a highly energetic person" , "Electrically charged" , "Broadcast in real time" , "Exist in evil" .)
