Reader's handiwork? (9)
I believe the answer is:
palmistry
'reader's handiwork?' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'reader's handiwork?' is the wordplay.
'reader' becomes 'palmist' (I've seen this before).
'handiwork?' becomes 'ry' (I am not sure about this - if you are sure you should believe this answer much more).
'palmist'+'ry'='PALMISTRY'
Can you help me to learn more?
(Other definitions for palmistry that I've seen before include "Prediction of the future from studying the hand" , "Telling the future by examining hand" , "Fortune-telling, otherwise known as chiromancy" , "attempt to predict futures" , "Kind of fortune-telling" .)
