The word 'systemically' is built upon the ancient Greek concept of sustēma, which denoted a complex whole formed by the combination or arrangement of parts. This root passed into Latin as systema and entered English as 'system'. The adjectival suffix -ic, of Greek origin, was attached to create 'systemic', meaning "relating to a system as a whole." Finally, the adverbial suffix -ally was appended, a hybrid of Latin and Old English, to describe an action performed in a comprehensive, all-encompassing manner. Thus, the term evolved from a concrete idea of a composite structure to describe an abstract, holistic mode of action or effect, particularly prominent in modern contexts like medicine (affecting the entire body) and social analysis.
