Etymology: The concept captured by this noun traces back to a philosophical tradition that seeks to identify the essence or fundamental nature of a thing. It is a formation rooted in the English suffix "-ness," which is commonly used to turn adjectives or demonstratives into abstract nouns expressing a state, quality, or condition. Here, the demonstrative "that" combines with "-ness" to form a term that signifies the quality or essence of "that" thing—its very "thatness." This construction plays on a longstanding philosophical idea, especially prominent in scholastic and metaphysical discourse, concerning the "whatness" or "thisness" of objects—their unique identity or essence that makes them what they are. While "thisness" often refers to the immediate, particular qualities of an individual object, "thatness" can be interpreted as a more distanced or general notion of essence, linked to the concept of "that" as a pointer to something specific but removed. The suffix "-ness" entered English in the Middle Ages, derived from Old English "-nes(s)" which formed abstract nouns from adjectives or pronouns. Combining it with "that," a demonstrative pronoun of Old English origin, was a natural, if somewhat rare, morphological process. The resulting noun is primarily philosophical or literary, used to articulate the quality or essence that makes an object distinctly "that" one. In usage, the term often appears in discussions of ontology and metaphysics, where thinkers analyze the properties that constitute the identity of entities. It has no fixed first recorded use but belongs to a family of similar abstract nouns that allow English to express nuanced philosophical ideas without borrowing foreign terms.
