Creative labour devilishly hard I know! (9)
I believe the answer is:
handiwork
'creative labour' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'devilishly hard i know' is the wordplay.
'hard i know' anagrams to 'HANDIWORK'.
Though, I am not sure how this is indicated.
Can you help me to learn more?
(Other definitions for handiwork that I've seen before include "one's doing" , "Manual creation" .)
