Etymology: "Identicality" is a plain English formation: "identical" with the suffix "-ity" added to turn an adjective into a noun for a state or quality. "Identical" itself comes from Late Latin "identicus," built from Latin "idem," meaning "the same," and the "-ity" ending traces back to Latin "-itas," which English borrowed through Old French to form abstract nouns from adjectives. The word therefore names the condition of being identical, that is, the quality of two things being exactly alike in every respect. Its structure shows its meaning directly: the root supplies sameness, and the suffix converts that sameness into something one can point to as a property.
