Synonym discussion

Sense: noun/1

All four words name places where the public can see fish or other sea animals, but they differ in scale and scope. 'Aquarium' is the broad, everyday word: it covers a small glass tank on a desk, a shop display, and large public buildings alike. 'Oceanarium' is narrower and more formal — it names a very large facility specifically for ocean animals, often big enough for dolphins or sharks; you would not use it for a home tank. 'Marine park' usually includes outdoor pools and animal performances as well as viewing tanks, while 'sea life centre' is the common British label for a paying tourist attraction with marine exhibits. For example, you might say 'I keep a small aquarium at home,' but 'The city is building a new oceanarium near the harbour.'

Etymology

LatinEnglish

Coined in early 20th-century English by joining 'ocean' with the Latin-style ending '-arium' (a place for, as in 'aquarium' and 'planetarium'). The word followed the pattern of 'aquarium' (1830s) and reflects the growing public interest in displaying large marine animals.
