Why this word is great
COADUNATION — [Noun] The union of disparate elements into a single, inseparable whole. From Latin coadūnātiō, from coadūnō ("to unite"), from co- ("together") + adūnō ("to unite"). Unlike "aggregation" (a loose gathering without dissolving boundaries) or "coalition" (a temporary alliance of convenience), coadunation is the alchemy of true merger. It is the way ink dissolves into water until no distinction remains, the way separate flames become one fire when their edges touch, or the way lovers, after years, begin to speak in each other’s cadences—proof that some unions are not merely arrangements, but transformations.
