Part of speech: adjective

Definitions

1. Relating to phenomena, particles, or forces that exist or operate at a scale smaller than that of the atomic level and going beyond typical atomic structure considerations
2. Pertaining to aspects or effects that occur within a scale beyond the atom, often involving subatomic or extraordinarily minute components or interactions
3. Describing processes, entities, or properties that transcend the usual atomic boundary and delve into realms smaller than atoms, including subatomic particles or ultra-microscopic structures

Etymology: "Ultraatomic" is a modern technical-sounding coinage built from familiar parts: the Latin prefix "ultra-", meaning "beyond" or "on the far side of," attached to "atomic," from the Greek "atomos," meaning "uncuttable" or "indivisible." The Greek word was a negative compound (a-, "not," plus tomos, "cutting"), and it was used by ancient philosophers such as Democritus for the smallest pieces of matter that could not be divided further. The ultra- prefix is used in English to form adjectives meaning "going beyond" a given range, as in "ultramodern" or "ultraviolet." Attaching it to "atomic" produces a word that points past the atomic scale toward smaller things. Because "atom" itself was once considered the last indivisible unit and was later shown to have a nucleus and electrons, the prefix now sits awkwardly on a word whose original meaning, "uncuttable," has been overtaken by physics. It is best understood as a formation from established parts rather than an older inherited word.
