Etymology: "Oceanologist" is a plain modern coinage built from two parts that each carry a clear meaning. The first part, "oceano-", comes from "oceanology," the study of the ocean, and the second, "-ist," is the suffix that marks a person who practises or specialises in a field, as in "biologist" or "geologist." Put together, the word names someone who studies the sea as a science. The pattern follows the usual route for scientific specialists: a field name is formed first, and then "-ist" is added to name the person working in it. Because the base "oceanology" is itself a modern formation built on the Greek-derived "ocean," the word is a product of recent scientific naming rather than an old term inherited from classical or medieval usage.
