Risky to accept dangerous order, creating difference of opinion (9)
I believe the answer is:
dichotomy
'difference of opinion' is the definition.
The answer and definition can be both related to thinking as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'risky to accept dangerous order' is the wordplay.
I cannot really understand how this works, but
'to' is found in the answer.
'order' could be 'om' (Order of Merit) and 'om' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
'creating' is the link.
Can you help me to learn more?
(Another definition for dichotomy that I've seen is " Division into two parts or kinds".)
