The abbreviation viz. (or viz without a full stop) is short for the Latin videlicet, which itself is a contraction of the Latin phrase videre licet, meaning "it is permitted to see".[1][2][3] It is used as a synonym for "namely", "that is to say", "to wit", "which is", or "as follows". It is typically used to introduce examples or further details to illustrate a point: for example, "all types of data viz. text, audio, video, pictures, graphics, can be transmitted through networking".[4]
