Origin and history of vivarium

"producing a distinct and strong impression on the mind," 1630s, from French vivide and perhaps also directly from Latin vividus "spirited, animated, lively, full of life," from vivus "alive" (from PIE root *gwei- "to live").

The extension to colors, "exhibiting the appearance of life or freshness," is from 1660s. In reference to memories from 1680s; of imagination, interest, etc. by 1853. Related: Vividly; vividness; vividity.

[Vividity's] ugliness is no doubt its misfortune rather than its fault ; but it is as natural to prefer vividness to it as to choose the one of two otherwise equal applicants who does not squint. [Fowler, "Modern English Usage," 1926] 

adjective and noun word-forming element, in most cases from Latin -arius, -aria, -arium "connected with, pertaining to; the man engaged in," from PIE relational adjective suffix *-yo- "of or belonging to."

The neuter of the adjectives in Latin also were often used as nouns (solarium "sundial," vivarium, honorarium, cucumerarium "a cucumber field," etc.). It appears in words borrowed from Latin in Middle English. In later borrowings from Latin to French, it became -aire and passed into Middle English as -arie, subsequently -ary.
