Etymology

The word "petrochemical" combines "petro-" (from Greek "petra," meaning "rock," referencing petroleum as "rock oil") and "chemical" (from "alchemy," via Arabic and Greek, meaning "substances derived through transformation"). The suffix "-ical" forms an adjective. The term emerged in the early 20th century to describe chemicals derived from fossil fuels, reflecting industrialization's reliance on petroleum.
