Etymology: "Oceanaria" is the plural of "oceanarium," a word formed from "ocean" plus the suffix "-arium," which is borrowed from Latin and used to name places associated with a particular purpose. The word was built by analogy with "aquarium," the older term for a tank of water animals, and it follows the same pattern: "aquarium" comes from Latin "aqua" meaning water, so the sea-focused version swaps in "ocean" to specify the watery world being displayed. Because "aquarium" was already an established model, "oceanarium" needed no separate invention. Its meaning is simply the sum of its parts: a place that displays ocean creatures, which is why the plural form "oceanaria" follows the Latin-style ending it shares with other "-arium" words.
