They don't believe American is open to taking bank jobs (8)
I believe the answer is:
atheists
'taking bank jobs' is the definition.
The answer and definition can be both people as well as being plural nouns.
Perhaps they are linked in a way I don't understand?
'they don't believe american is open' is the wordplay.
I cannot really understand how this works, but
'american' could be 'a' (common abbreviation - e.g. in organisation names) and 'a' is found in the answer.
'is' is found in the answer.
This may be the basis of clue (or it may be nonsense).
'to' acts as a link.
Can you help me to learn more?
(Other definitions for atheists that I've seen before include "Godless people" , "They believe deities don't exist" , "They don't believe in a deity" , "They deny the existence of a god" , "Heathens" .)
