Videlicet

adv. in other words, that is (Latin)

Viz (also "viz.", with a period) and videlicet are adverbs used today as synonyms of "namely, precisely, that is to say". Videlicet is Latin for "one may see; clearly, evidently", while viz is a corrupted abbreviation of the former. They introduce a specification or a more detailed description of something stated before; often, as with a syntactical-descriptive colon, this is a list. Though both forms survive in many modern languages, viz is far more common in English than videlicet. Viz is traditionally read aloud as "namely" or "to wit", not phonetically as . In writing, it is now usually followed by an unnecessary period (see below).

Viz is a popular British adult comic magazine that has been running since 1979.At its best, the comic's style parodies the strait-laced British comics of the post-war period, notably The Beano and The Dandy, but with incongruous language, crude toilet humour, black comedy and either sexual or violent story lines. It also sends up tabloid newspapers, with mockeries of articles and letters pages. It features competitions and advertisements for overpriced 'limited edition' tat, as well as obsessions with half-forgotten celebrities from the 1970s and 1980s such as Shakin' Stevens and Rodney Bewes. Occasionally it satirises current events and politicians, but has no particular political standpoint. Its success has led to the appearance of numerous rivals crudely copying the format Viz pioneered; none of them has managed seriously to challenge its popularity. It once enjoyed being the third most popular magazine in the UK, but circulation has since dropped to just over 300,000 (from 1.2 million). This is mainly because its comic remit has become broader and its format more commonplace, but also partly due to the fact that price has increased sharply to £2.80 and it is now published 'monthly' ten times a year.
