Etymology

The word "geological" combines three morphemes:

  1. "Geo" derives from Greek "gē," meaning "Earth." This root appears in many Earth-related terms (e.g., geography, geocentric).
  2. "Log" comes from Greek "logos," meaning "study" or "discourse," commonly used in scientific disciplines (e.g., biology, psychology).
  3. The suffix "-ical" transforms the noun into an adjective, indicating relevance to the field.
    The term emerged in the early 19th century as geology became a formal science, reflecting the study of Earth's physical history through its layers and processes.
