Etymology: "Diachronicity" is built from three Greek elements: "dia", meaning "through" or "across", "chronos", meaning "time", and the English suffix "-icity", which forms nouns of quality from adjectives ending in "-ic". Read literally, it names the quality of something that runs across time. The word belongs to a family of coinages formed on the same pattern in linguistics in the early twentieth century, when scholars needed precise terms to separate the study of a language at a single moment from its study through successive stages. The contrasting term "synchronicity" is the older sibling of the pair, and the two were shaped together. The Swiss linguist Ferdinand de Saussure drew the basic distinction between the synchronic and the diachronic in his lectures, published posthumously in 1916 as "Cours de linguistique générale". Where the synchronic describes a system as it stands at one moment, the diachronic follows change through time, which is why the adjective "diachronic" is usually the one that appears in scholarly work, with "diachronicity" naming the quality of that approach.
