geology
UK: dʒiˈɒlədʒi | US: dʒiˈɑːlədʒi
n. the science that studies the Earth's physical structure, substance, history, and processes
n. the geological features of a specific region
The word "geology" combines the Greek root "geo-" (meaning "Earth") and "-logy" (meaning "study of"). It emerged in the late 18th century as a scientific discipline focused on Earth's composition and history. The term reflects the Enlightenment-era systematization of natural sciences, where "-logy" became a standard suffix for fields of study (e.g., biology, psychology).
