How does one read out “viz.”? “Namely”, “to wit”, or something else entirely?
According to this answer, the correct approach is to translate as you vocalize, so you would say "namely" instead of pronouncing it as "viz". However, I have never (knowingly) heard anyone do this, and would probably simply pronounce it as "viz" myself.
Also, anyone who knows of Viz Comic (warning, not entirely suitable for work) - which essentially means anyone who was in their teens or twenties and living in the UK since the 1980s - will enjoy the associations brought back by hearing the word.
