Pronunciation

  • Ecclesiastical: [aˈkʷaː.ri.um][1]

Forms

aquārium n (genitive aquāriī or aquārī); second declension[1]

Etymology

It is from Latin aquārius (“of water”), used as a noun in the neuter.[2][3] The adjective is formed from aqua (“water”).[3]

Earliest recorded meaning

Cato (234–149 BC) uses it in his work on agriculture for a reservoir or watering place.[4][5]

Semantic evolution

In Classical Latin it was a source of water, a watering place for animals.[2][4][3] Medieval Latin used it for a canal or water channel, which a charter of Louis the Pious calls by this name,[6][7] and the statutes of Marseille for a sink or drain.[7] The TLL lists Italian acquaio and French évier among its Romance continuants.[8]

English took it as a noun in 1830 for an artificial pond for water plants, and by 1853 for a glass tank in which water animals are kept.[3]
