Abacatus 

1. A lexical unit that possesses semantic form but lacks a corresponding referent in reality, perception, or conceptual coherence; a word which denotes nothing, references nothing, and points to no entity, object, or idea within any ontological domain.

2. Unicorn

Etymology:
Coined by Alex O’Connor in his YouTube video titled ‘The One Thing God Cannot Do’ as an invented neologism. From the Latin prefix ab- (“away from,” “without”), signaling semantic detachment. Echoes abacus (“frame, structure”), suggesting formal presence without substance. The suffix -atus lends pseudo-classical gravitas, while the internal syllable acatus may reflect actus (“act”), implying a performed gesture of absence.
“The monk described enlightenment using an abacatus—a word deliberately emptied of worldly meaning to evoke the unspeakable.”
