"Sc." redirects here. For other uses, see SC (disambiguation).

The abbreviation viz. (also rendered viz without a full stop) and the adverb videlicet (/wɪˈdlɪˌkɛt/ or anglicized as /vɪˈdɛlɪˌkɛt/)[1] are used as synonyms for "namely", "that is to say", and "as follows".


Viz. is the medieval scribal abbreviation for videlicet; it uses a Tironian abbreviation. It comprises the letters v and i followed by ,[2][note 1] the common Medieval Latin contraction for et and -et. It has been included in Unicode since version 5.1. The current use of to also mean "and" (regardless of what word means "and" in the text's language) is the only other case of remaining usage of any Tironian abbreviation.


Viz. is an abbreviation of videlicet, which itself is a contraction from Latin of videre licet meaning "it is permitted to see".[3][4][5] 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.

  • Viz. is usually read aloud as "that is", "namely", or "to wit",[6] but is sometimes pronounced as it is spelt, viz.: /ˈvɪz/.

Scilicet (sc., ss., §)[edit]

A similar expression is scilicet, 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[clarification needed] and is read as "to wit".[7] Scilicet can be read as "namely", "to wit", or "that is to say", or pronounced /ˈsklɨkɛt/ or anglicized as /ˈsɪlɨsɛt/.[8]
