Why “dissimilitude” is a great word
DISSIMILITUDE — [Noun] The quality or state of being fundamentally dissimilar in nature or character. From Latin dissimilitūdō, from dissimilis ("unlike"), from dis- ("apart, not") + similis ("like, similar"). First attested in English in the early 15th century. Unlike "difference," which notes discrete points of unlikeness, or "similitude," its polished antonym of likeness, dissimilitude names an abstract, often profound divergence in essence. It is the chasm between the mechanical tick of a clock and the organic rhythm of a heartbeat, the uncanny valley between a waxwork and a living face, and the irrevocable gap between a memory and the present it recalls—a quiet testament that some gulfs are measured not in degrees, but in kind.
