Definition & Meaning: Arium Word Root

The root word -Arium originates from the Latin -ārium. It is generally used to refer to ‘a place or container connected with, or employed for, some purpose.’ For example, an aquarium is a place where aquatic animals are kept. The word vivarium means a place in which to keep living things, derived from:

  • Viv(ere): To live
  • Arium: A place where
  • Viv+arium: A place in which to keep living things

Therefore, it is fair to say that words with the root -Arium mostly refer to ‘a place where,’ forming corresponding nouns.

Example sentence: On 18 February 1852, the Council of the Zoological Society of London (UK) commissioned the building of an Aquatic Vivarium (the original term for a fish tank or enclosure) at London Zoo.
