I've always said it " VI-varium"

and

"Viv" like "Liv" or "give"

Right or wrong ? thoughts ?

VIve, as in aLIVE...short for VIvarium. Abbreviation before a vowel!!!

Interesting....is there a English Grammer cite we can access ?...NOT disputing....just trying to take it all the way to the basket.

The Merriam-Webster dictionary on my iPad pronounces it Vi (long I sound) but no specific emphasis on any syllabol.

This site says it the way you mentioned and the way I've been saying it viv (short I sound) same as viv for short.
