To rob thus shows no humanity! (5)
I believe the answer is:
robot
'no humanity' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
'to rob thus' is the wordplay.
'to rob' can be anagrammed to 'ROBOT'.
But, I'm unsure how the anagram is indicated.
'shows' acts as a link.
Can you help me to learn more?
(Other definitions for robot that I've seen before include "programmed servant" , "Man-made man - man-made machine" , "Mechanical worker" , "Factory worker, perhaps" , "Mechanism that can move like a human" .)
