No believer observing robbery? (7)
I believe the answer is:
atheist
'no believer' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'observing robbery?' is the wordplay.
'observing' becomes 'at' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'robbery?' becomes 'heist' (heist is a kind of robbery).
'at'+'heist'='ATHEIST'
Can you help me to learn more?
(Other definitions for atheist that I've seen before include "Disbeliever in gods" , "Godless person" , "Person who does not believe in existence of a god" , "I don't believe" , "Unfaithful type" .)
