viz.

• vid., videl.

From Medieval Latin viꝫ, from Latin vidēlicet (“that is to say, namely”), short for vidēre licet (“it is permitted to see, look (it is) legal”). The ‘z’ was originally not a letter but a common Middle Latin scribal abbreviation ꝫ that was used for -et, specifically a Tironian note. The symbol resembled ‘z’, or rather 3 and Ȝ, and hence is thus represented in type. Compare ⁊, the Tironian symbol for Latin et (“and”) (in isolation, not as suffix).

Conventionally read out as namely, to wit, or occasionally videlicet. Otherwise pronounced as follows:

• IPA^(key): /vɪz/

• Audio (Southern England):

  (file)

• Rhymes: -ɪz

viz. (not comparable)

1. Videlicet: namely, to wit, that is to say, specifically, as an illustration.

     As to (b), the joint intention, like any intention, commits the intending agents to carry out its content, viz. to act.

viz. is used to introduce a list or series. It differs from i.e. in that what follows normally expands upon what has already been said, rather than merely restating it in other words; and from e.g. in that completeness or near-completeness is suggested, rather than a small selection of examples.

It’s nonrestrictive, so it should be set off from the sentence, usually by commas.
