Noumenon
/ˈnuːmɪnɒn/noun
A thing as it is in itself, independent of how it appears to any observer.
The Greek roots
Literally: “the thing being thought”
The story of the word
Kant's term for the thing in itself, set opposite the phenomenon, the thing as it shows up in experience. The Greek is a passive participle, 'that which is being thought', from the verb behind νοῦς, mind. Plato's forms are the ancestor of the idea, but Kant reversed its value: for Plato the intelligible world is what can truly be known, and for Kant the noumenon is precisely what cannot.
