What does categorical mean?
Categorical is an adjective describing statements or positions that are absolute, unqualified, and emphatic. When someone issues a categorical denial or makes a categorical refusal, they are asserting something with total confidence, leaving no room for doubt, conditions, or exceptions. The word derives from the Greek kategoria, meaning accusation or predication, which also gave us 'category' — and this philosophical heritage remains visible in its second, more specialised sense: in philosophy, especially in the work of Immanuel Kant, categorical describes concepts that apply universally and unconditionally, as in his famous 'categorical imperative'. In everyday use, however, categorical belongs chiefly to formal registers such as politics, law, and journalism, where speakers want to convey certainty and finality. Its antonyms include conditional and equivocal, making it a precise tool for signalling unwavering commitment.
Absolute and unconditional; stated emphatically without any possibility of exception or doubt.
"He gave a categorical guarantee that the data would not be shared."
Typically found in formal contexts such as legal statements, political denials, and academic writing.
(Philosophy) Relating to categories or classes, especially in Kant's sense of concepts that apply unconditionally to all experience.
"The categorical imperative requires that one act only according to principles one could will to be universal laws."
This sense is largely confined to philosophical discussion.
A categorical denial doesn't just say 'no' — it slams the door so firmly that philosophers borrowed the word to describe the very categories reality itself falls into.

Etymology of categorical
Categorical traces back to the Greek katēgoria, meaning 'accusation' or 'assertion', from katēgorein ('to accuse' or 'to predicate'), formed from kata- ('down/against') and agoreuein ('to speak in the assembly'). Aristotle used the term for his fundamental classes of predication, and the word passed into Latin as categoria before entering English in the late 16th or early 17th century. Its sibling words include 'category', 'categorize', and 'categorically', all sharing the same Greek root.
