What does incogitable mean?
Incogitable means too profound, obscure, or complex to be understood or conceived. It describes things that exceed not merely a particular person’s knowledge but, often, the apparent reach of human thought itself. The word is associated especially with philosophy, theology, and formal literary writing, where it conveys the limits of reason or the mystery of an existence or universe that cannot be comprehensively grasped. In contemporary English it is uncommon, and “unfathomable” or “incomprehensible” will usually sound more natural. Even so, it remains effective for describing an intellectual or metaphysical problem that resists clarification. Its association with the Latin cogito, familiar through Descartes’s phrase “cogito, ergo sum,” also gives it a distinctive intellectual character.

"The causes of the collapse remain incogitable despite years of investigation."
Formal and literary; especially associated with philosophy, theology, and abstract description.
Something beyond the limits of human thought or comprehension.
"For some philosophers, the nature of consciousness is the incogitable at the heart of the problem."
Now chiefly literary or philosophical, and commonly used in the definite form “the incogitable.”
Descartes declared, “I think, therefore I am”; “incogitable” asks what happens when even thought itself lies beyond comprehension.

Where does incogitable come from?
The word comes from Latin incogitabilis, meaning “not capable of being thought” or “not to be conceived,” formed from in- (“not”) and cogitare (“to think”). It entered English during the early 17th century in philosophical and theological contexts. Its relatives cogitate, cogitation, and cogito all trace to the same Latin root for thought.
