Etymology: Geochemical is a modern compound built from two pieces with a long history apiece. The first, "geo-", comes from Ancient Greek "gaîă" and "gê", meaning "earth", and appears in English in words like geography and geology. The second, "chemical", traces back through New Latin "chēmicus" and "chēmia" to Arabic "al-kīmiyāʔ" (alchemy), which itself was borrowed from Medieval Latin "alchēmia" and ultimately from Ancient Greek "khumeíā", a term whose earlier meaning is uncertain. The older alchemists' art of transforming matter gradually narrowed into the modern science of substances, and "chemical" arrived in English from that scientific Latin. Geochemical is therefore formed simply by joining "geo-" to "chemical", placing the study of the earth's composition beside the study of substances in general. The "-al" ending is the same adjective suffix found in "chemical", which descends through Old French and Middle English from Latin "-ālis".
