aquarium

\ \ [19] Aquarium is a modern adaptation of the neuter form of the Latin adjective aquārius ‘watery’ (a noun aquārium existed in Roman times, but it meant ‘place where cattle drink’). Its model was vivarium, a 16th-century word for a ‘place for keeping live animals’. This was the term first pressed into service to describe such a place used for displaying fish and other aquatic life: in 1853 the magazine Athenaeum reported that ‘the new Fish house at the London Zoo has received the somewhat curious title of the “Marine Vivarium”’; and in the following year the guidebook to the Zoological Gardens called it the ‘Aquatic Vivarium’. Within a year or two of this, however, the term aquarium had been coined and apparently established.
