Viz.


The abbreviation viz. (or viz without a full stop), short for the Latin videlicet, is used as a synonym for "namely", "that is to say", "to wit", or "as follows". It is typically used to introduce examples or further details to illustrate a point.

Viz. is shorthand for the adverb videlicet. It uses Tironian notes, a system of Latin shorthand developed c. 63 BC. It comprises the first two letters, "vi", followed by the last two, "et", using the z-shaped Tironian "et", historically written ⁊, a common contraction for "et" in Latin shorthand in Ancient Rome and medieval Europe.

Viz. is an abbreviation of videlicet, which itself is a contraction from Latin of videre licet meaning "it is permitted to see". The spelling viz. is the continuation of an abbreviation using Tironian et (vi⁊), the z replacing the once the latter had fallen out of common use.

In contradistinction to i.e. and e.g., viz. is used to indicate a detailed description of something stated before, and when it precedes a list of group members, it implies (near) completeness.

A similar expression is scilicet (from earlier scire licet), abbreviated as sc., which is Latin for "it is permitted to know". Sc. provides a parenthetic clarification, removes an ambiguity, or supplies a word omitted in preceding text,  while viz. is usually used to elaborate or detail text which precedes it.

In legal usage, scilicet appears abbreviated as ss. or, in a caption, as §, where it provides a statement of venue and is read as "to wit".Scilicet can be read as "namely", "to wit", or "that is to say", or pronounced /ˈsklkɛt/ or anglicized as /ˈsɪlsɛt/.
