What does oceanic mean?
Oceanic is an adjective meaning relating to the ocean or characteristic of its environment. It is used in scientific, geographical, and environmental contexts to describe oceanic waters, oceanic crust, oceanic climates, and the organisms that inhabit the sea. The word can also suggest great vastness or breadth, as in an “oceanic” plan or expanse, although this figurative use is less common than the literal scientific one. In ordinary writing, “marine” may be more familiar, while “oceanic” is especially appropriate when emphasizing the open ocean, deep water, or oceanography. Its broad associations with depth, scale, and the sea give it a sense that is both descriptive and evocative.

Where does oceanic come from?
The word “oceanic” was formed in the 17th century from “ocean” and the suffix “-ic,” meaning “pertaining to” or “characterized by.” “Ocean” itself comes through Latin from the Greek ōkeanos, the ancient name associated with the world-encircling sea. Related English terms include “oceanographer” and “oceanography,” which developed from the same Greek root through the Latin word oceanus.
