Etymology: "Atomicism" is a plain formation: the adjective "atomic" with the suffix "-ism", which turns an adjective into a name for a doctrine, system or school of thought. The suffix comes from Greek "-ismos" through Latin "-ismus" and entered English largely through French, so it is the same ending found in words such as "realism" or "mechanism". The base word carries the older history. "Atomic" descends from "atom", which comes from Greek "atomos", meaning "uncuttable" or "indivisible", from "a-" (not) and "temnein" (to cut). Ancient thinkers such as Leucippus and Democritus proposed that matter was made of such tiny indivisible units, and the idea of the "atom" as the smallest building block is what "atomicism" names.
