This thing is potentially revealing (7)
I believe the answer is:
insight
'this thing is potentially revealing' is the definition.
The definition and answer can be both related to thinking as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'this thing is potentially revealing' is the wordplay.
'thing is' can be anagrammed to 'INSIGHT'.
But, I am not sure how this is indicated.
Can you help me to learn more?
(Other definitions for insight that I've seen before include "Perspicacity" , "Clear or deep perception of a situation" , "Deep understanding" , "The ability to perceive the true nature of something" , "comprehension" .)
