The story

A variant of atomi, the plural of atomus (‘hypothetical particle posited as an ultimate and indivisible component of matter; mote of dust in a sunbeam’) treated as a singular form. Atomus is derived from Latin atomus, from Ancient Greek ἄτομος (átomos, “indivisible”, adjective), from ᾰ̓- (ă-, prefix forming terms having an opposite sense) + τομ- (tom-) (stem of τέμνω (témnō, “to cut”), ultimately from Proto-Indo-European *temh₁- (‘to cut’)) + -ος (-os, suffix forming nouns of action or result).
