Etymology
The word 'incoherence' is built upon the Latin foundation of 'coherence', which itself derives from 'cohaerere', meaning "to stick together". The prefix 'in-' negates this core concept, literally creating the sense of "not sticking together". This physical metaphor was seamlessly adopted into intellectual discourse, where ideas that do not logically connect or "stick together" are described as incoherent. Thus, the term evolved from a literal description of physical separation to an abstract assessment of logical disunity and unintelligibility.
