I was mucking about in my Hebrew lexicon, trying to figure out what Eliphaz's name meant. (Eliphaz the Temanite is one of Job's "friends" who offered cold comfort).
"Eli", of course, means God. "Phaz" is apparently an old word similar to an Arabic word that means "light, active, agile" and also is used to mean "refine," as in purified gold.
The root word is פזז (pazaz).
Which reminded me of "pizzazz." Several different dictionaries list this word as "etymology unknown."
Light, active, agile, and like refined gold. Sparkly. I think "pizzazz" comes from pazaz.
