The word “viz.” (with the period after it) is pronounced or spoken also as NAMELY. Cute, right? Its more formal term is videlicet from the Latin videre (to see) + licet (it it permissible).
This is how the dictionaries define it:
viz. |viz| or said as |ˈnamle| adverb
- namely; in other words (used esp. to introduce a gloss or explanation). Example: Do you still remember the first music reproducing media, viz., the music box and the player piano? (1)
- used before something that you are giving as an example. Example: She limited her suggestions to the subjects she knows best, viz [=namely], layout and typography. (2)
