according to my Latin dictionary it means :

it is clear that, obviously, of course

maybe in Spanish you say claro

It does not appear in the French dictionary

buena suerte!

viz.
That is to say, namely. Commonly used **to introduce examples**.
**This expression lies ambiguously between i.e. and e.g.**, in the following way: The list of examples that follows it may not be an exhaustive list, in which case it means something like e.g. Alternatively, the list following it may be exhaustive or complete, from some point of view, in which case viz. means something like i.e. This expression is a good way of covering your ass when you don't understand a thing well enough to define it, but you think that you can give a list that probably covers all cases.
Viz. is an abbreviation of the Latin adverb **videlicet**, which originally meant something like ``clearly,'' and came from the expression **videre licet**, meaning *"to be able to see"*

You may ask:
**`where does the z come from?**' What z? Oh! That z. The one in the abbreviation. Well, this may be hard to believe, but back in the Middle Ages, before the time when life started to get hectic, books were reproduced by hand. Even monks, who have centuries to work, would get writer's cramp, so they would come to another long and frequently-appearing word like videlicet, peer down towards the end of it and think: `everyone knows what the word is.' Like good sports they'd start out to write it, but by the time they'd written v i they would begin to LOSE HEART, so they'd just sort of write a squiggle that looks like a resistor in a circuit diagram, except that those things didn't exist yet. Instead, they saw that it resembled a z (especially a script z), so they got into the habit of writing "v i z"."

Un cordial saludo.
