The part people get wrong

Watch for an unstressed vowel that is hard to hear.

Same family: geologic, geological, geologically, geology, geochemistry. If you can spell one, the shared part carries to the others.

Where it comes from: “Geologist” comes from the Greek roots geo- meaning “earth” and -logist from logos meaning “study” or “reason,” so a geologist is literally a person who studies the earth. The word became common in English in the 18th–19th centuries as scientists began to systematically study rocks, fossils, and the history of our planet.
