orthomolecular

The term is a modern scientific compound, coined in the mid-20th century by chemist Linus Pauling. It combines the Greek-derived prefix ortho-, meaning "correct" or "right," with the adjective molecular, which pertains to molecules. The literal construction implies "correct molecules" or "the right molecules." This etymological logic directly informs its modern medical definition: an approach that aims to correct disease by establishing optimal, "right" concentrations of molecules (like vitamins) that are natural to the human body, contrasting with introducing foreign pharmaceutical agents.

Structure: ortho (correct) + molecular (relating to molecules) ortho: From Greek orthos, meaning "straight, correct, right." In English, it functions as a combining form denoting correctness or straightness. molecular: From Latin molecula, a diminutive of moles ("mass"), combined with the English adjectival suffix -ar. It functions as the core noun base modified by the prefix.
