Whiz has a few definitions. It’s a verb meaning to move swiftly or to make a sound like an object moving swiftly. As a noun, it usually means one who has remarkable skill in something, and it sometimes denotes a whizzing sound. It’s also a noun in the phrase take a whiz, which means urinate. It’s used in the interjection gee whiz, which expresses amazement or surprise. And there’s whiz-bang, usually an adjective meaning very effective in a novel way.

Whizz is an alternative spelling of whiz in all its definitions. Wiz is an alternative spelling of whiz in the sense one who has remarkable skill in something. Because these spellings came later and have no definitions of their own, they always bear replacement with the longer-established whiz.
