Etymological and semantic contradiction in modern terms "atom and molecule" With solution by proposing new ancient terms

This paper examines the etymological and semantic contradictions in the modern scientific terms "atom" and "molecule." The term "atom," derived from the ancient Greek atomos ("indivisible" or "uncuttable"), is fundamentally mismatched with contemporary physics, which has established that atoms are divisible composite structures made of subatomic particles (protons, neutrons, and electrons). Similarly, "molecule," from Latin molecula ("tiny mass"), lacks precise structural criteria and fails to clearly distinguish different scales and states of matter. To resolve these inconsistencies, the author proposes a revised taxonomic framework drawing from the ancient Vaiśeṣika school of Indian philosophy (circa 600 BCE), particularly the concepts developed by Kaṇāda. The paper suggests: Reallocating "atom" exclusively to truly indivisible fundamental particles (fermions and bosons), restoring its original Greek meaning. Adopting Aṇu to describe the composite, divisible particles currently called atoms. Introducing Sañyuktāṇu (synthesized through Sanskrit grammatical rules) to replace "molecule," denoting bonded multi-particle systems unified through the Vaiśeṣika concept of sañyoga guṇa (conjunction or bonding force). This unified nomenclature bridges classical philosophy with modern science, eliminates conceptual paradoxes, and creates a more logically consistent and historically respectful terminology for physics and chemistry. The proposal highlights the value of integrating insights from both Greek and Indian atomistic traditions.
