Viz is the abbreviation of the Latin word “videlicet,” which means “namely.” Viz is a synonym for “namely” or “to wit” or “that is to say.” It is used to highlight or make more specific something that has previously been indicated only in general terms and is mainly used in legal and technical writing because it saves space.
For example: "There were several problems, viz: leaky roof, dangerous electrical system, and broken windows."
